Circa 1760 Van Cortlandt mansion on 27 acres over the Hudson, with a 100 guest minimum every day and a published 1:00 pm rain call.
Monteverde at Oldstone will not take a wedding under 100 guests, on any day of the week. That is the venue’s own published minimum and it is the first thing to check against your list. What the 100 buys is a circa 1760 mansion built by the Van Cortlandt family, restored, sitting on 27 wooded acres at 28 Bear Mountain Bridge Road in Cortlandt Manor with the Grand Lawn ceremony site looking down the Hudson. Anyone can book it. There is no membership and no sponsor. The estate publishes something most Westchester venues will not: an actual rain protocol, with the final wet weather decision made by 1:00 pm on the wedding day. It also publishes hard vendor rules, including two named lighting companies and a ban on client supplied linens. What it does not publish is a price. The $320 per person figure in circulation belongs to a marketplace, not to the venue.
The estate publishes rules but not prices. The 100 guest minimum, the vendor restrictions, the 1:00 a.m. after party limit and the 1:00 pm rain call are all first party and all firm. The $320 per person and the 20% administrative fee come from Here Comes The Guide rather than from the estate, and must be confirmed at a tour. Ask what the six hours cover, what the extra hour really costs, and which pavilion capacity applies to a seated dinner.
The venue’s home page, weddings page and wedding FAQ at monteverdeatoldstone.com, plus the Here Comes The Guide listing and The Knot marketplace listing. All fetched 11 September 2026. Checked September 2026. First party means the business’s own site or rate card. Marketplace means The Knot, WeddingWire, Zola, Wedding Spot or similar. Nothing here is averaged or estimated.
The 100 guest minimum applies every day of the week, which rules the estate out for small weddings. Two first party capacity figures for the tented pavilion conflict, 350 seated on the weddings page against 360 for dinner and dancing on the FAQ. Tours are weekday appointments only, and pricing is not given any other way.
The pavilion comes with a permanent floor, a parquet dance floor, a tent liner, studio lighting, a vanity restroom trailer and a generator, all included. That list is the difference between a structure the estate maintains and a marquee that arrives on a lorry the week before, along with the porta cabins and the cable runs.
It is also the largest space. The weddings page puts it at up to 350 seated for dinner and 450 for cocktails. The FAQ page says it holds up to 360 for dinner and dancing. Both figures are first party and they do not match, so ask the estate which of its own two numbers governs a contract. The mansion first floor is the smaller option, at 150 seated without dancing and 110 with.
The mansion figures are worth reading twice. One hundred and fifty seated without dancing drops to 110 once a dance floor is in the room. Since the venue will not take a wedding under 100 guests, the mansion on its own works for a narrow band of guest lists.
The venue publishes the deadline: the final wet weather decision is made by 1:00 pm on the wedding day, with the mansion, the terrace and a secondary tent as the alternatives to the Grand Lawn. Here Comes The Guide adds that ceremonies and receptions move into the tented pavilion in bad weather, with cocktail hours moving into the mansion.
A published deadline is worth more than a reassuring sentence on a tour. It means somebody has thought about who decides and when, and it means you can plan the morning around it instead of arguing about it.
Catering and alcohol are in house only, and only Monteverde’s licensed bartender may serve alcohol. Lighting must come from one of two named firms, Stortz Lighting or LNJ Tech Services. Linens must be ordered through approved vendors and clients may not supply their own. All of that is on the venue’s own FAQ page, and a separate vendor information page exists.
Read that as a cost structure rather than a nuisance. Every rule above removes a line you could otherwise have shopped for. Price the lighting quote from both named firms early, because there is no third option.
Ask about the linen rule in particular. Being unable to supply your own linens is unusual, and it removes a line couples often use to control cost. Find out which approved vendors are available and what the range actually is.
Neither the weddings page nor the wedding FAQ publishes a per person rate, a package price, a site fee or a food and beverage minimum. Pricing is given at appointment only tours.
Here Comes The Guide lists $320 per person and up, covering six hours of venue rental, food and alcohol, with extra time at $3,000 per hour. The same source lists a 20% administrative fee. Both are marketplace figures that the venue has not confirmed. The Knot displays a generated average of around $26,417 with a per head figure derived from it, which is a platform calculation rather than a price anyone quoted, and we are not treating it as one.
The venue publishes that an after party must not end later than 1:00 a.m. and is limited to two hours. Here Comes The Guide separately puts a music curfew at 11:00 p.m., which the venue does not state. The two are consistent if reception music stops at 11 and an after party runs to 1:00 a.m., but that reading needs confirming.
Here Comes The Guide also states one wedding per day maximum. The venue’s own pages do not address exclusivity at all, so that is a marketplace claim about a property with a mansion and a pavilion. Ask directly.
Mansion events run year round. The FAQ describes the tented pavilion as year round too, while Here Comes The Guide says pavilion receptions run April to October. The hip and frame tent over the terrace is described as available April to October. Treat the venue’s own page as the authority and confirm the date you want.
The estate keeps a century old grape arbour, a stone patio for cocktails and three named dining rooms inside the house: the Grand, the Veranda and the Governors’. The architect of the original house is not published anywhere we looked.
The house itself is dated to around 1760 and attributed to the Van Cortlandt family, and a century old grape arbour is still on the grounds. The architect is not published, and neither is a date for the restoration. Ask on the tour, and ask which rooms are original.
Appointments run Monday to Friday, 10:00 am to 3:30 pm. A weekend appointment has to be booked by 5:00 pm on the preceding Friday. Since pricing is only given at a tour, that schedule sets how quickly you can actually get a number.
One small oddity: the Director of Events contact published on the site is a personal gmail address. It is not a problem in itself, but keep your own copy of every quote and every confirmation rather than relying on that inbox.
