Conference and banquet facilities
Prices, terms and permits
You can find the prices of the facilities, as well as terms and instructions related to the prices and leasing on these pages.
A preliminary booking is valid for two weeks, after which the booking must be confirmed. When you have confirmed the booking with us, we will send an invoice for the booking charge by post. The term of payment for the booking charge is 14 days. We will send a separate final invoice approximately one month before the event. Services with an extra charge, such as the arrangement of furniture and the use of the grand piano in Tenaille von Fersen, will also be invoiced in the final invoice. The prices include the use of the facilities and their equipment on the day booked; in conference facilities, in the whole day bookings 9 am to 5 pm, in half day bookings from 8 am to 1 pm or from 3 pm to 8 pm, and in banquet facilities from 10 am to 1 am.
The rental of our facilities does not include outdoor facilities. In Suomenlinna, all activities taking place outdoors are subject to a permit. Due to this, the organiser of an event including a marriage or raising glasses outdoors needs a permit granted by the Governing Body of Suomenlinna.
The organiser of a function should note that Suomenlinna is both an active city district with its own inhabitants and events and a popular attraction with tourists during the high season. Outdoor areas will not be allocated to the private use of a customer.

Booking terms and instructions
As a significant monumental fortress and a unique environment, Suomenlinna provides a memorable environment for conferences and banquets. The following booking terms and instructions have been prepared to ensure peace for the inhabitants and to increase the comfort and safety of visitors.
The tenant of the premises undertakes to comply with these booking terms and instructions. The Governing Body of Suomenlinna reserves the right to request additional information on the event organised by the tenant. The Governing Body of Suomenlinna reserves the right not to accept a booking request and cancel a booking if the terms and conditions are not complied with or if the Governing Body of Suomenlinna has reason to suspect that the premises are used against our terms.
The Governing Body of Suomenlinna only leases the facility. Customers are themselves responsible for arranging catering, for example. Only people over the age of 18 can rent the conference and banquet facilities in Suomenlinna.
The liability of the Governing Body of Suomenlinna as a facility lessor for any personal injury to its customers or damage to other movable property is determined according to the general principles concerning damages.
Customers are responsible for injury or damage they or their guests cause to persons, buildings, furniture or other equipment in the leased conference/banquet facility.
Fire safety and other safety issues
Customers are responsible for the safety of guests and for maintaining order in the leased premises, the adjoining routes and outdoor areas. In each location, there is a room-specific exit map with which the lessee must become familiar.
The customers must ensure that they have all the necessary permissions of the authorities and insurance policies required by the nature of the event. A prior notice of the event must be given to the police or the rescue department if this is required by the nature of the event, and the customer is responsible for having a sufficient number of security officers.
Handling fire is prohibited on Suomenlinna. Outdoor candles may not be used, and candles may not be lit indoors. Only electric lanterns and electric candles are allowed. The prohibition also applies to all pyrotechnics, smoke machines and sparklers. Arranging private fireworks on Suomenlinna is forbidden. Smoking is only allowed outdoors.
The only exception to this rule are professional catering services using fuel gel for heating chafing dishes. Professional catering services are allowed to use chafing dishes heated with fuel gel burners if the burners are supervised. Staff must always be present whenever fuel gel is used. If the customer is taking care of the catering without a professional caterer, only the use of electric chafing dishes is allowed.
The kitchens of the conference or banquet facilities are intended only for heating food. Frying is prohibited. The cooker hood must be turned on. The fire alarms in the historic premises are very sensitive, and the inappropriate use of the kitchen may trigger the alarm.
Where the customer is in breach of the rental terms and conditions stated in the booking terms and instructions document, the Governing Body of Suomenlinna has the right to invoice the customer in arrears for the breach of contract. For example, the following are defined as examples of breaches of contract: exceeding the agreed rental time and an emergency call by a maintenance person or a guard in a disturbance situation caused by the customer. Breaches related to fire safety, such as burning candles or smoking, will always be subject to a minimum charge of EUR 500.
The rent of the facility consists of a booking fee and a final payment. When the customer confirms the preliminary booking, the reservation becomes binding. After the booking has been confirmed, we will send the customer a reservation fee invoice. The final payment will be paid approximately one (1) month before the event. In case the booking is made less than 45 days before the event, the entire rent of the facility will be invoiced at the same time.
The Governing Body of Suomenlinna has the right to cancel a booking if all the payments have not been made in full by the due date. An unpaid invoice is not a cancellation: The debt remains even if the customer decides to cancel the reservation.
If the customer cancels the booking at least six (6) months before the event, 50 % of the paid booking fee will be reimbursed. If the booking is cancelled later than six (6) months before the event, the booking fee will not be reimbursed.
If the rent, i.e. the booking fee and the final payment, has been paid in full in advance and the customer cancels the booking at least one (1) month before the event, the final payment will be reimbursed with subtracted office costs of EUR 34. In this case, the customer will lose the money for the booking fee. If the cancellation takes place later than 30 days before the event, no payments will be reimbursed.
