Muuksi stronghold hill was established on a naturally suitable small cape. At the location of the stronghold, the western side is up to 10 metres higher than the surrounding ground.
Its main task was most likely to be the coastguard and lighthouse.
The stronghold area was protected by a sharp and high klint from the north and by an arched stone wall from the south. Today, the courtyard of the stronghold is surrounded by a partially preserved low sodded wall.
Archaeological excavations have proven that the site was first inhabited during the first millennium BC, the castle was established at the end of prehistory, and some of the findings are probably from the 11th to 13th century.
