St Francis church was originally part of a Franciscan monastery, and was alongside the Royal Palace. Today it can be found close to the Venetian Palace. It consists of a three-sided apse with a small chapel off the south side. Buttressing supported the external walls. It was built in the early years of the 14th century with funding supplied by Henry II, King of Cyprus who reigned from 1285 to 1324.
Henry's reign was far from peaceful. He saw the fall of Acre in 1291, his own imprisonment from 1306 to 1310, and the disbandment of the Knights Templars in 1313. In the latter years of his reign, however, not only did he fund the building of this church, but he saw the fortification of Famagusta, and the start of the rebuilding of St Nicholas Cathedral.References:
Ängsö Castle was first named as "Engsev" in a royal charter by king Canute I of Sweden (r. 1167-1196), in which he stated that he had inherited the property after his father Eric IX of Sweden. Until 1272, it was owned by the Riseberga Abbey, and then taken over by Gregers Birgersson.
From 1475 until 1710, it was owned by the Sparre family. The current castle was built as a fortress by riksråd Bengt Fadersson Sparre in the 1480s. In 1522, Ängsö Castle was taken after a siege by king Gustav Vasa, since its owner, Fadersson's son Knut Bengtsson, sided with Christian II of Denmark. However, in 1538 it was given by the king to Bengtsson's daughter Hillevi Knutsdotter, who was married to Arvid Trolle.
In 1710, the castle was taken over by Carl Piper and Christina Piper. Ängsö Castle was owned by the Piper family from 1710 until 1971, and is now owned by the Westmanna foundation. The castle building itself was made into a museum in 1959 and was made a listed building in 1965. It is currently opened to visitors during the summers.
The castle is a cubical building in four stores made by stone and bricks. The lower parts is preserved from the middle ages. It was redecorated and expanded in the 1630s. The 4th storey as well as the roof is from the expansion of Carl Hårleman from 1740-41. It gained its current appearance in the 1740s.
