Oitbackan kartano is a manor estate on the shore of Lake Loojärvi in Kirkkonummi, about a half-hour drive from central Helsinki. Organisers rent the buildings for weddings, family celebrations, company parties and sauna evenings. The Orangery holds a ceremony for 100 guests, the stable hall holds a party for 130, and a private sauna room with a fireplace room suits 10 to 15 people. The venue is rented for the whole weekend, from Friday to Sunday.
Seminars and company events
The manor takes company parties, Christmas parties, team evenings and photo shoots. The site also lists art exhibitions among past events. It does not describe meeting rooms, projection equipment or conference formats, so it fits a team day, a client reception or a staff party better than a technical seminar. The venue states that there is no sound system on site, so a company bringing a presentation or a band needs to arrange its own equipment. The sauna with its fireplace room works for a small management group or a team evening of 10 to 15 people.
Weddings and receptions
Weddings are the first offer on the site. The ceremony takes place in the Orangery, which holds 100 guests, and the reception is held in the Art Nouveau stable, which holds 130. The couple has the buildings for the whole weekend, so there is time to prepare on Friday. Hirers decorate the rooms themselves and choose their own style. The manor says that it looks after the setting and the hirers look after the party.
Rooms and capacities
The Orangery: ceremonies for 100 guests. The Art Nouveau stable: parties for 130 guests. The sauna with its fireplace room: about 10 to 15 people. The rental includes the party spaces, basic cleaning and basic supplies. The estate also rents storage and workshop space, which is a separate offer from event hire.
Catering
The client arranges food, drinks, music and decoration. Hirers can bring their own caterer or use the network of partners the manor has built up over time. The site does not mention an in-house kitchen or a catering menu.
History and setting
The manor has been owned by the Kiseleff family of Helsinki since 1859. Its buildings are a white main house, an Art Nouveau horse stable and the Orangery, and the site describes the estate as more than 150 years old. It remains a working farm and forestry unit, not a museum. Its nature management received the international Wildlife Estates label in 2026. A carriage museum is part of the estate, and the park and the stone buildings are open to the events held there all year. Winter and autumn dates are described as flexible.
Getting there
The address is Kiseleffin puistotie, 02510 Oitmäki, on the southern shore of Lake Loojärvi. The drive from central Helsinki takes about half an hour. To ask about free dates, call the number on the site or send an e-mail, and say the date and the type of event. A site visit can be arranged on request.
