I didn't know about this palace before postcrossing. I've seen the 1st card on Ninoca's cards and added it to my favorites. Now we've a postcrosser from Algarve, Tiago, in the portuguese community and he sent me these two cards.
Sittuated in the village of Estói, nearby Faro, it has around four hectares length, with French-inspired gardens, decorated with statues and trees. The Palace, in Rococo Style is decorated with panels of glazed tiles and wide glass windows. - in: http://www.getportugal.com/en/poi-palacio-de-estoi-15529
