The whole face of the Huécar Gorge was once lined with hanging houses. Today only three remain, and these were thoroughly restored at the beginning of the 20th century. They are in the traditional Gothic style, and some original elements can still be seen in the part that houses the Museum of Spanish Abstract Art . There is a wealth of wooden details on the interior. The exterior entranceway is in the Renaissance style and was originally part of an old palace in Villarejo de la Peñuela. The house on the left hand side (the restaurant kitchen) is known as the Casa de la Sirena (house of the mermaid).
