Razgrad clock tower

The clock tower in the city of Razgrad, northeastern Bulgaria, is about 25 metres (82 ft) high and dates to the Ottoman era. It is among the vast number of clock towers spreading in Bulgaria after the rise of the first clock towers in the Western Balkans during the second half of the 16th century, the earliest evidence of which was the clock tower in Plovdiv in 1611. The clock towers in Bulgaria performed multiple tasks as they were used not only for timekeeping, but for signaling danger and fire emergency, and as watch towers for military purposes and defense. In the 18th, and especially the 19th, centuries, these towers served mainly craftsmen and traders in their efforts to keep work hours in check to prevent competition and work exploitation.
