The Cannon Bastion was built by the Palatine Alexius Thurzo in about 1540. Its cannons would protect the bridges over the river Váh and so-called Upper (Water) Gate of Trenčín with the adjoining part of the town´s entrenchment. In the adjacent annex (with the chapel) used to be a gun powder mill.print last edit 06.9.2009
