When the building was built , the designers and architects were aware of the seismic conditions of the area , based on past experience of earthquake incidence and its damaging effects on buildings particularly in metropolitan cities like Skopje . They had thus taken due care to account for the seismic parameters based on the magnitude of earthquakes as design factors in the design of the building . This is one reason due to which the palace survived the effects of the 1963 Skopje earthquake ; earthquake was of magnitude of 6.1 that occurred on July 26 , 1963 causing death of 1070 apart from injuries to many people . Ristiḱ Palace was one of the few buildings that survived when nearly 70 % of the buildings in the town were destroyed . Most of the buildings were built in Skopje with vertical load bearing walls and this is one reason attributed for the collapse . Other reasons mentioned for the collapse being use of the materials used in construction . In the case of the palace , modern building standards were followed . Ikonomov House was built in 1922 by architect Boris Dutov , Todorov House built in 1927 by the architect Novakovic . in the same area which became the elite area of Skopje
