Located on top of a 10th-century fortification, the Castle of St Louis was built as a Crusader fortress by King Louis IX in 1254. It was the first inland castle constructed in Saida and like many Crusader structures, largely ruined by the Mamluks. Currently obscure and unattended, it still is worth a visit for its nice views over the city, particularly for those who like to explore. To reach the area, climb up the stairs east of the Fakhr el-Dine Palace and turn right to go around the castle. There, you will find a low wall with an entrance gate. You need to climb through a hole to get up on the roof of the castle. Apparently, there is a tunnel leading all the way to the sea castle, which nowadays is inaccessible.
