Aside from preventing invasions, the spotting of fires was an important job of any tower guard. As such, it's appropriate that a fire station was eventually built here along the former site of the city’s watchtowers. This brick Neo-Gothic beauty was completed in 1887, and features a tall tower with a tiny observation deck at its peak. Also don’t miss the charming wrought-iron sign hanging from the facade on Masztalarska Street. Lovingly refurbished, the station building is still in use by the fire department, and a modern station from 2004, handsomely designed to match its predecessor, stands just on the other side of the former moat.
