Dąbrówka Starzeńska boasts ruins of a 16th-century castle, which towers over a bend in the San River. This castle was built roughly on a square plan, with three bastions (missing only in the southeast corner). The original castle corresponds to today's ruins in the northwest part, while the remaining traces indicate expansions made over the subsequent centuries. The latest construction work here took place in the 20th century, adding new residential wings. The damages were brought by the Soviet occupation in 1939, the German takeover in 1941, and a subsequent Soviet occupation in 1944. The fate of the ruins was sealed by the Ukrainian Insurgent Army, which blew up the remnants in February 1947, preventing their use in battles.
