The Noble Assembly building is considered one of the best examples of civil architecture in the classical style in the Russian provinces of the mid-19th century. It was originally built in the 1780s as a residential house and belonged to the famous Kostroma merchant M.P. Durygin. In the early 19th century, the building fell into disrepair, and it was decided to reconstruct it. In 1837-1838, a major renovation was carried out according to the project of provincial architect Magnus Maximilianovich Prave. A southern wing was added to the existing structure, which housed the assembly hall. The openings were enlarged, new grand entrances were created, the facade was updated, and the interiors were almost completely redesigned. It was during this time that the building received a luxurious cast-iron staircase.

Today, the Noble Assembly is part of the Kostroma State Historical, Architectural, and Art Museum-Reserve, which includes five buildings in Kostroma and 16 branches in the region. The history of the museum-reserve begins with the Noble Assembly in 1891.

Exhibitions dedicated to the life of Kostroma and Kostroma nobles in the 19th century are currently held in the halls of the Noble Assembly. Here, one can learn about the visit of Emperor Nicholas II to Kostroma.

Additionally, interactive history lessons about the nobility are conducted daily for children and adults, and art and theater studios for schoolchildren and students are also successfully operating.
