Fort Coenraadsburg, Military fortress on St. Jago Hill in Elmina, Ghana.

Fort Coenraadsburg is a small fort on St. Jago Hill in Elmina, about 200 metres from Elmina Castle. The Dutch rebuilt it in the 1660s in local sandstone on the site of a Portuguese fortified chapel, replacing earlier earthworks. It has no commercial warehouses, only military structures, and today serves as an inn and restaurant.

The Dutch built the fort in the 1660s on a hill where the Portuguese had raised a fortified chapel between 1555 and 1558. In 1637 the Dutch bombarded Elmina Castle from this hill, then fortified it with earthworks. Director General J. Valckenburgh replaced the earthwork with a permanent fort of local sandstone, named Coenraadsburg. The Dutch ceded it to Britain in 1872.

The fort's design and layout tell stories of how colonial powers organized their coastal presence in the region. Walking through its spaces shows the practical arrangements that supported military and trading operations along the shore.

The fort sits on St. Jago Hill about 200 metres from Elmina Castle and is open from 9:00am to 4:30pm. The climb up the hill is steep and the ground uneven, so sturdy shoes help. The fort now houses an inn and a restaurant.

The Dutch never lost Fort Coenraadsburg to an enemy; it passed to Britain in 1872 only through the sale of the Dutch Gold Coast. Unlike other forts on the coast, it never served the slave trade, functioning purely as a military post and later as a prison for European convicts.
