Castell de Samalús, Medieval castle in Cànoves i Samalús, Spain.

Castell de Samalús, also known as Can Bori, is a rectangular three-storey building crowned with battlements, machicolations and gargoyles. Its stone facade has a central pointed-arch portal, three neo-Gothic windows separated by slender columns, and a trefoil window flanked by two slate-roofed towers. A large round tower stands at the left, and two 16th-century windows from the old mas are preserved on the south facade.

The building originated as the old Mas Cavaller. In 1749 Isabel de Gat i Cavaller married Josep Marià de Bòria i de Llinàs, whose family gave the estate the name Can Bori. Around 1895 Francesc de Puig took part in a wager with relatives to convert his property into the finest medieval-style castle; the prize went to Josep Maria de Pallejà's Mas Saleta.

The name Can Bori comes from the Bòria family, who acquired the estate through the 1749 marriage of Isabel de Gat i Cavaller to Josep Marià de Bòria i de Llinàs. Around 1895, Francesc de Puig took part in a wager with two relatives to see who could turn his estate into the finest medieval-style castle; the Mas Saleta in Sant Hilari Sacalm won. Two 16th-century windows from the old masia are set into the south facade, one with a zigzag arch and carved human faces.

The building stands near the Samalús nucleus in Cànoves i Samalús, in the Vallès Oriental. It is a private property, so access to the interior is not open to the public; the stone façade, the pointed-arch portal and the round tower on the left can be seen from outside. The 16th-century windows are on the south façade.

Around 1895, owner Francesc de Puig made a wager with two relatives over who could turn his estate into the finest medieval-style castle; his rivals' projects were the Torre de Riu in Alp and the Mas Saleta in Sant Hilari Sacalm, and Mas Saleta won. Two 16th-century windows from the old masia survive in the south facade, carved with zigzag arches, plant motifs and human faces.
