The exhibits in this hall are part of the personal collection of the two-time Olympic champion in classical wrestling Boyan Radev. The presented objects are grouped into three categories: personal medals and decorations, church utensils and Roman stone sculpture.

Over 170 objects from the personal collection of Boyan Radev are part of the collection of the National Museum of Natural History. Among the exhibits are also his personal awards, international medals and diplomas. Along with them, icons with cryptic inscriptions and monuments of church art from the 19th century, as well as samples of Roman stone sculpture from the 2nd-3rd centuries have found their deserved place in the museum space.

These exhibits with historical significance are also of undeniable value because of the way they were acquired by the museum institution. In the modern history of Bulgarian museum work, this is one of the rare examples of donation.
