The Church building was launched on the 2nd of August 1925 and lasted for 5 years. The building works were managed by architect Rudolf Fischer. The Ossuary Church consists of 2 parts, upper and lower. The upper one has two floors. There are frescoes of saints warriors pictured on the church’s walls – St. Demetrious of Thessaloniki, St George, St. Theodore Stratelates, St. Archangel Michael and others. Their painters are Dimiter Gyudzhenov, Dechko Mindov, Prof. Nikola Kozhuharov, Prof. Georgi Hristov. The iconostasis’ woodcarving is a work by Radomir Mandov, Vladimir Naumov and sculptor Stefan Stoyanov. The terrain’s relief allowed the architect to build a ground floor where the ossuary is situated. Inside the church there is a plague with an inscription “Built during the Reign of His Majesty Boris III – Tsar of Bulgarians”.
The Church-Monument was officially sanctified on August 3rd, 1930 by Sofia Bishop Stephan in Minister of War General Mayor Nikola Bakardzhiev, the Mayor of Kyustendil and representatives of the Holy Synod presence.
