Altena Castle, Medieval castle ruins in Almkerk, Netherlands.
Altena Castle in Almkerk consists of medieval fortress remains featuring a moated hill with visible foundation traces and hollow areas. These archaeological traces mark where defensive structures once stood on the site.
The castle was first documented in 1230 when Dirk III pledged it to Count Floris IV of Holland. This event established its role in regional feudal politics during the medieval period.
The castle reflects early construction techniques from before 1200, when stone and tuff were still common building materials in the region. Visitors can observe these ancient methods in the preserved foundations and structural remains.
The site is accessible and located at Altena's Laantje 2-2a in Almkerk, Noord-Brabant. Visitors should expect uneven ground and exposed archaeological features when exploring the ruins.
In 1393, the castle became a refuge for individuals involved in the murder of Aleida van Poelgeest. This connection to a significant crime led to a major siege of the location.
