This is one of the original 13 city gates in Old Town. Built in 1475. The tower was intended to be an attractive entrance into the city, instead of a defensive tower. The gate was used to store gunpowder in the 17th century, hence the name Powder Tower or Powder Gate. We were part of a walking tour and didn't get a chance to walk inside. I would have liked to have seen inside. Still, a landmark not to be missed.
