The archive has three historical buildings at its disposal – Tolli 4, 6 and 8. The largest of them is the early classicist customs and packaging building Tolli 8 (architect J.C. Moor) built at the end of the 18th century. Previously, the city palace of Peter I was in the same spot.

Tolli 6 is a medieval residential building, probably built in the second half of the 14th century.

Tolli 4 consists of two residential buildings built in the first half of the 15th century, which were connected later, probably in the second half of the 18th century.

The quarter where Tolli 4, 6 and 8 property is located is in the neighbourhood of the supposed stopover for foreign merchants that was once located around the Oleviste Church. Presumably after 1310. this area was merged with the main core of the city during the reconstruction of the city fortifications. At the end of the 14th century, the whole quarter belonged to one owner and was transferred as such to the new owner in 1400.

In 1415 began the division of the block into individual properties, and from about that time, it became possible to talk about the history of this specific property.

The USUS team investigated the existing condition of the building on the order of the Tallinn Property Department, including clarifying structural safety and highlighting important deficiencies. It was evaluated whether the use of the building for the intended purpose and manner is safe and gives recommendations for further activities. The study of the condition of the roof’s supporting structures and covering material explained their technical condition and the period of need for repairs.
