Tavira Castle is worth a visit even be it only for the views out over the city, the countryside and down to the sea.
The foundations for the defensive systems were built during the Moorish period between the 8th and 13th centuries. After the Christian Reconquest, they were improved on the orders of king Dinis (1261-1325), thereby integrating Tavira into his strategy of reinforcing the national lines of defence. In 1640, maintenance work was carried out.
Currently, some sections of the wall still remain including a part of the citadel that retains its medieval characteristics and the Arch of Misericórdia (Compassion).
