Saint Thomas Tower is a large bastioned watchtower in Marsaskala. It was built above the shore on the seaward face of the headland of il-Hamriga in Marsaskala. It is a substantial fortification intended to prevent the landing of troops in the sheltered anchorages of Marsaskala Creek and St Thomas Bay. Construction of the tower was approved in July 1614, weeks after the raid of Żejtun, in which an Ottoman fleet managed to land at St Thomas Bay. The tower was named after a chapel dedicated to St Thomas which stood close to where the tower now lies.
The tower has very thick walls and has four pentagonal bastioned turrets projecting outwards on each corner. The tower's entrance was through a vaulted doorway with a wooden drawbridge. The drawbridge is still partially intact and it is the only original one to have survived in Malta. The tower is surrounded by a rock-hewn ditch.
After the De Redin towers were built, St Thomas had Żonqor and Xrobb l-Għaġin Towers in its line of sight, but these are now either in ruins or completely demolished.
In 1715, St Thomas Tower was reinforced by the addition of a battery on the seaward face. During the French blockade of 1798–1800, the tower was stormed and captured by Maltese insurgents.
The tower remained in use by the British until the 19th century. At some point, the tower was also used as a prison.
References:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
