The shortest street in Sofia (just 60 metres), ‘Malko Tarnovo’ is nestled between the tall buildings surrounding it and resembles a staircase rather than a street. As a result, it has preserved many historical secrets over the years. The street stands on top of artefacts and archaeological finds from Ulpia Serdica, dating back 6,000 years. According to archive photographs, in the 19th century, at the junction of ‘Malko Tarnovo’ and ‘Moskovska’, there was a clock tower, much to the displeasure of the local clockmakers, who believed it hindered their trade. And according to more recent urban legends, Tsar Boris III was so fond of having a drink at Bar Luna, which was located on this street, that he would even visit it in his slippers. Most passers-by on the street today probably have no idea that there is a door here leading to the cells of the State Security, where ‘enemies of the people’ were ‘processed’ before being sent to camps.
