One of Bulgaria’s oldest riverside towns, Vidin is home to the only entirely preserved medieval Bulgarian castle. Perched impressively on the riverbank, its striking pose, thick ring walls, stout towers and solid gates form a fortress known as Babini Vidini Kuli, which means Granny Vida’s Towers. Around the castle rose a fairy-tale town of 25 minarets, domes and other charming architecture of the period. Though many of these features have been shadowed by today’s city, Vidin retains its charms. Today it is largely an agricultural and trade center renowned for its wines.
