The Blue House (Shtepia e Kalter) dates back to the 19th century. It is located between the fortress and the city center, within the individual housing area under the fortress known as Varosh. The walls of the house were reconstructed with present day materials, but it’s authentic adobe look has been preserved. Meanwhile, the walls of the exterior facade are colored blue, which makes the house one of its kind. The blue color in local culture is seen as autochthonous and it manages to awaken the collective memory of cultural heritage among the citizens of Prizen.
The house continues to be inhabitable to date, with the Kadriaj family currently residing there.
