Long Island runs estate to waterfront, with Gilded Age mansions on the North Shore offering stone architecture and formal gardens, while South Shore and East End properties give you ceremony sites that face the bay or ocean.
If you need higher capacity with water views, Riviera Waterfront Mansion offers room without feeling packed, while smaller properties like The Royalton Mansions keep guest counts lower to preserve the private estate feel.
1. 360 East at Montauk Downs
Ocean views from every angle make 360 East at Montauk Downs feel less like a venue and more like the edge of the world.
The ceremony site sits on white sand with nothing between your guests and the water but open sky.
If you want a beach wedding without the hassle of permits or weather unknowns, this setup gives you the look with the structure of a full venue behind it.
The sand stays groomed, the chairs stay anchored, and you get the ocean without fighting it.
2. Bourne Mansion
Built as a Vanderbilt estate, Bourne Mansion still carries that old-money scale: stone walls, red tile roof, and a lawn big enough to host a full ceremony outside before moving everyone in.
The grounds give you room to spread out without feeling like you’re in a ballroom all night.
The outdoor space holds larger guest lists without the crowding most historic venues force on you. You can seat ceremony and cocktail hour outside, then bring everyone inside for dinner without losing the estate feel.
3. The Mansion at Oyster Bay
The Mansion at Oyster Bay features a circular drive and fountain that photograph exactly the way you’d hope a Gold Coast estate would.
Inside, the ballrooms run formal and tall-ceilinged, the kind of space that holds a seated dinner without feeling tight.
If you like symmetry and want a venue that looks finished without much added décor, this one does the work for you.
The architecture is the feature, so you can keep florals simple and still get the grand wedding look.
4. The Mansion at Glen Cove
Gatsby-era brick and stone make The Mansion at Glen Cove feel like a period piece, right down to the tiered fountain out front.
The landscaping is formal but not stuffy, and the grounds are big enough to walk through with guests between ceremony and reception.
If you want a venue that feels like an estate wedding but don’t need waterfront views, this one trades the water for gardens and a fountain that photograph just as well.
The brick warms up the look compared to the white stone mansions, which suits fall and winter weddings better.
5. The Royalton Mansions
The Royalton Mansions feel private in a way most Long Island venues don’t. The white façade glows at night, and the reflecting pool and fountain create a symmetry that reads formal without being stiff.
If you want a wedding that feels exclusive without booking an actual private estate, this setup mimics that intimacy.
Guest counts stay smaller here, which keeps the space from feeling empty and lets you spend more per person without blowing the budget.
6. Oheka Castle
Oheka Castle is the chateau wedding: symmetrical gardens, reflecting pools, and a yellow stone façade that belongs in France, not Long Island.
The formal gardens give you multiple ceremony sites, and the building itself holds receptions that feel like you rented a palace.
If your budget allows it and you want a venue that needs no explanation, this one delivers.
Oheka sits at the top of the Long Island market, so if you’re splitting budget between venue and everything else, know that this choice takes a big piece of the total.
7. Peconic Bay Yacht Club
Peconic Bay Yacht Club puts the ceremony right on the water, with docks and boats visible from every angle. The deck setup gives you an outdoor space that feels nautical without leaning too hard into anchor motifs or sailcloth.
If you want a waterfront wedding that reads casual but still holds a full reception, this one keeps the vibe relaxed while giving you the structure of a yacht club behind it.
The tent setup protects against weather without blocking the view.
8. Flowerfield Celebrations
Flowerfield Celebrations runs green and garden-heavy, with mature trees forming a natural backdrop that needs minimal added décor.
The ceremony site sits outdoors with enough landscaping to feel lush without requiring you to bring in extra florals to fill the space.
If you want a garden wedding but don’t want to rent a private estate, this venue gives you the look at a lower cost.
The greenery does most of the work, so you can keep floral arrangements smaller and still get a full garden feel.
9. Water’s Edge
Water’s Edge combines waterfront views with a modern ballroom that feels more yacht club than country estate. The floor-to-ceiling windows let you keep the water visible during dinner, and the chandeliers add a sculptural element without reading traditional.
If you want a waterfront wedding that skips the historic mansion feel, this one gives you the water with cleaner lines and a brighter interior. The modern design suits couples who want elegance without heavy draping or wood paneling.
10. RGNY Vineyard
RGNY Vineyard gives you rows of grapevines and open lawn without the stiffness most estate venues carry. The outdoor ceremony sits right in the vines, and the tent setup keeps the reception casual and approachable.
If you want a vineyard wedding on Long Island without traveling upstate, this one delivers the look with a laid-back vibe that suits smaller guest lists.
The space feels more rustic than formal, so it fits better with farm tables and string lights than gold chairs and tall centerpieces.
11. NYIT De Seversky Mansion
NYIT De Seversky Mansion offers red brick and formal gardens without the waterfront price tag.
The circular driveway and landscaping photograph like a private estate, and the building itself holds receptions that feel grand without requiring you to rent an entire chateau.
If you want a historic mansion wedding but Oheka sits outside your budget, this one gives you similar architecture and grounds at a lower cost. The brick exterior warms up photos compared to white stone, which suits fall weddings better.
12. The Inn at Great Neck
The Inn at Great Neck features a glass-roofed ceremony space that feels indoor and outdoor at once. The chandeliers and white draping keep the look formal, while the natural light softens the room in a way most ballrooms can’t match.
If you want an indoor ceremony that doesn’t feel closed off, this setup gives you weather protection without losing brightness. The glass ceiling works year-round, which makes it a good option for winter weddings that still want daylight.
13. The Mansion at West Sayville
Red brick and white columns give The Mansion at West Sayville the symmetry of a colonial estate, with stone terraces and lawns big enough to hold a full ceremony outside before moving guests in.
The grounds photograph formal without needing heavy added décor.
If you want a historic mansion wedding with waterfront views, this one sits directly on the Great South Bay with acreage and architecture that stand on their own.
The brick exterior works year-round but photographs especially well in fall when the color matches the season.
14. The Barn at Old Bethpage Village Restoration
Wood beams and barn siding at Old Bethpage Village Restoration give you the rustic venue look with the benefit of a working historical site behind it.
The space holds draping and chandeliers without losing the barn feel, so you get refinement inside a structure that still reads agricultural.
If you want a barn wedding that skips the farm drive out east, this one sits closer to Nassau County and costs less than most waterfront venues.
The barn interior needs fabric and lighting to soften it, so budget for rentals that fill the height and warm up the wood.
15. Riviera Waterfront Mansion
The lawn runs wide enough for an outdoor ceremony, and the ballroom inside holds up to 350 guests without feeling packed.
If you need capacity and want waterfront without losing the estate look, this one delivers both. The size suits larger guest lists that would overwhelm smaller venues, and the water placement gives you ceremony backdrops most big ballrooms can’t match.
16. Sands Point Preserve
Sands Point Preserve sits on a bluff with water views and stone architecture that photograph like a European estate.
The lawn ceremony setup keeps the building as your backdrop, and the grounds give you multiple outdoor spaces without needing to move guests far between events.
If you want a historic estate wedding with views but prefer the castle look over red brick, this one trades the mansion interior for stone and a preserve setting that feels more secluded than most Long Island venues.
Venue Styles
Long Island splits cleanly between estate weddings and waterfront properties, with a third lane for couples who want something less formal.
The Gold Coast mansions run brick or stone with formal gardens, most built during the Gilded Age when the North Shore was where old money summered.
These sit inland or on bluffs, so you get architecture and acreage but not always direct water access.
The waterfront venues cluster on the South Shore and out east, where ceremony sites face the bay or ocean. These tend to run modern or yacht club in style, with glass and clean lines instead of carved stone.
Vineyards and barns fill the gap for couples who want outdoor ceremony sites without the estate price.
Whether you envision having your nuptials with a picturesque vineyard as the backdrop, walking down the aisle on a breathtaking beach, celebrating in a glamorous Gilded Age mansion or dancing the night away in a centuries-old rustic barn, it’s all possible on Long Island.
Average Wedding Costs
Long Island wedding costs run higher than most of the state outside Manhattan, with the biggest variable being how far east you go.
The Hamptons and North Fork push venue costs up, while Nassau County and mid-Suffolk stay closer to the state average.
Guest count drives the total faster than anything else.
A larger guest count at a waterfront venue will cost more than a smaller event at the same property, since most venues price by the head for food and bar, and those minimums stack quickly.
Season matters less here than it does upstate. Fall books first, but winter weddings at indoor venues cost about the same once you account for heating instead of tent rentals.
Guest Accommodations
Some Long Island venues include on-site hotel rooms or have partnerships with properties next door, which cuts down on guest logistics if you’re bringing people in from out of state.
The estate venues that offer overnight stays let you extend the weekend into a mini destination wedding without leaving the grounds.
For venues without rooms attached, most sit within 15 minutes of a hotel cluster.
The North Shore properties near Glen Cove and Great Neck have the densest hotel options, while the East End venues out past Riverhead rely more on inns and bed-and-breakfasts that book out early during wedding season.
Block rates matter if you have a large out-of-town guest list. Start calling hotels early to lock in group pricing, especially for summer and fall weekends when Long Island sees both wedding traffic and beach tourism.
