The Monument to Vasil Levski (Bulgarian: Паметник на Васил Левски , "Pametnik na Vasil Levski") in the centre of Sofia, the capital of Bulgaria, is one of the first monuments to be built in the then newly liberated Principality of Bulgaria. It commemorates the hanging of Bulgarian national hero and major revolutionary figure Vasil Levski on the same spot on 18 February 1873.
Monument to Vasil Levski was the second monument to be built in the Principality of Bulgaria.
It says it was "one of the first." That could mean second, or it could not. The article doesn't mention second, so the AI doesn't connect the dots.
