This is the view from the 14th century Palácio National or the the Paço da Vila de Sintra, which is in the town centre. Classified as a national monument, the guide book refers to this building as a 'one of Portugal's best palaces ... a gradual multiplication of buildings, with different styles, that is largely responsible for the enigmatic enchantment of this ancient palace, dominated by great twin chimneys atop the kitchen that constitute as authentic ex-libris of Sintra'.
Maybe I missed something that was in the interior of this palace, since by the time we got there, it was closed, but its exterior was rather drab, and the twin chimneys looked like inverted ice-cream cones.
