From the 15th century, this entrance was made up of two towers linked by a wooden structure. A moat and draw-bridge enhanced the defences. According to the plans drawn up in 1745 by a military engineer named Franque, to entre the town it was necessary to pass under 2 more gates overlooked by a bastion.The magnificent scale model acquired by the Tourist Information Office in 1978 and exhibited at the Arvo gives a precise idea of the site's layout in 1632.An essential visit is the old cemetery created in 1784 where former mayors and public figures of the town rest in peace.
