St Kentigern's Church is a scheduled monument in Lanark, South Lanarkshire. It is believed that the church was founded by St Kentigern himself shortly before his death in 603 AD. There is documentary evidence of its existence, however, dating back to 1150 AD when King David I granted it to the monastery of Dryburgh. Pope Gregory VIII took the church into his own protection in 1228.
The architecture of the present church is 13th century and the site is known to have been occupied by a previous church. The church, which was once attended by William Wallace, is now in a state of disrepair, despite having had repair work completed recently.
Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
