Palacio Nacional da Pena
Another taxi ride took us to Sintra, a very pretty area, home to several historic places, not the least of which is the amazing Pena Palace. It's very popular with tourists, especially after Sintra was awarded world heritage site status by UNESCO. Fortunately I had booked a Palace entry ticket before leaving home so after a hectic walk up and down the forest path from the parking area we were able to skip the queues and get a bus up the very steep hill. The palace itself is stunning, and its royal contents even more so.
