They were built exclusively in the European part of the Ottoman Empire, particularly in Bosnia and Herzegovina, as an Islamic variation of the Western European bell tower, and have become a symbolic architectural feature of Bosnia and Herzegovina. They were usually constructed with a large clock on one or more faces of the tower (most often on all four sides) so that time could be read by as many inhabitants of the settlement as possible. The term sahat-kula is an archaic expression in the Bosnian language and refers to specific structures built predominantly in the territory of Bosnia and Herzegovina.

According to a 16th-century French travel writer, the first sahat kula was erected in Skopje between 1566 and 1572. Sahat kule were most commonly built in the central zones of the čaršija, usually next to mosques, as endowments of individual vakifs (waqf founders). However, they are also found in other locations, such as the sahat kula in Maglaj, which was erected within the lower courtyard of the Maglaj fortress, and those in Tešanj, Gradačac and Počitelj.
