Casa Fuerte
Adeje, Spain · built 1556
Casa Fuerte de Adeje (Adeje Strong House) is a fortified building complex in Adeje, Tenerife, Spain. A strong house was constructed around 1556 to protect a sugar mill, and the site was subsequently significantly expanded. The building complex was renovated in the 1700s before a fire left it in ruins in 1902, a state in which it remains today, leading to its inclusion on the Spanish Redlist of endangered heritage in 2019. Since then some restoration work has taken place and part of the monument has been opened to the public for daily visits.
