we had two full days in lisbon & spent one of them going around to different towns, one of the towns that we stopped at was sintra. sintra was such a cool little town, full of color, really different architecture & multiple estates & castles. we stopped at two different palaces: palace of sintra & the pena national palace.
the palace of sintra is totally different from pretty much any other palace i have ever seen. the entire outside is white while the inside is decorated heavily in intricate, colorful tiles & the two cone shapes on the roof were over the kitchen.
plus, it's a unesco world heritage site :)
