When constructed, the building claimed to have the world's largest four-faced chiming clock. This is one impressive city hall building.It is important to look at the building close up to see all the fine detail carved in the stone. It remained the tallest building in Minneapolis until the Foshay Tower's construction in the 1920s. A downtown Minneapolis icon stopped running Monday morning, but don't worry it was all planned. The tower, which soars 345 feet above ground, was the tallest structure in the city until the Foshay Tower was built in the 1920s. Located at 101 N Cedar Avenue, the National Farmer's Bank of Owatonna is one of those places that left us in complete awe.
