I had a day layover in Lisbon on the way home, so I made the most of it by walking around from my hotel, near the Marquês de Pombal monument, to Baixa, the historic downtown.
After sitting for a bit in Praça do Comércio, I decided to walk over to São Jorge Castelo (St. George Castle), up on a hill. But, I got totally lost in the Alfalma district of Lisbon, which was a maze of narrow sidewalks with constant stairs and turns. I kept going up since the Castle was somewhere above me, but buildings blocked the view. Eventually I emerged and got my bearing, but I decided it was too late to go in the castle (the grounds were closing in 30 mins) so I headed back to the city center. Eventually I decided to just ride the subway back to the hotel since my feet were tired.
