The Oslekov House was built from 1853 – 1856 for the wealthy businessman Nencho Oslekov, who was a producer and trader of textiles. In his workshops were sewn clothes for the participants in the April Uprising of 1876. Following the Uprising, he was arrested and hung due to his participation.
The house was built be the craftsman Mincho, and the murals were painted by the Renaissance mason Costa Zograf, both from the town of Samokov. It was designed in an asymmetrical shape due to the small building area. There is a central area, and an additional wing. Three cedar columns support the second floor, and the house features a wooden staircase on the outside.
The Oslekov House is a fascinating house with unique construction and stunning frescoes. This is undoubtedly one of the most beautiful houses in Koprivshtitsa. Since 1956 it operates as an ethnographic museum.
Returned to its owners in 2013, the museum's inventory is no longer present on site, but you can still visit it and admire its architecture.
