tongue of land stretching into the sea from the coast of Zealand towards the coast of Scania. The castle consisted of a square curtain wall with a number of stone buildings inside. The stone building in the northeastern corner contained the king's residence. The building in the southwestern corner contained a large arched banquet hall. The building in the southeastern corner possibly served as the chapel. Large portions of the walls of Krogen are contained within the present-day Kronborg Castle. King Christian III had the corners of the curtain wall supplemented with bastions in 1558–1559. Frederick II's Kronborg As a consequence of developments in the military technique of the era and the improved striking power of the artillery, it became clear that it was necessary to modernize the fortifications of Krogen.
