Castelo de S Jorge
On the first really nice day, I walked to the castle, which is most worth going up because of the view. The line meandering at the entrance was a little daunting, but it was moving fast. The castle is open, with only a café and a museum inside. Inside, it resembles the Maltese San Anton Garden a bit: you can walk on similar fragmented stone slabs. There are fewer flowers, but more peacocks.
Botanical Garden of the University of Lisbon
The Botanical Garden of the University of Lisbon is 140 years old and 40,000 square meters. Unfortunately, one part was just closed due to renovations. The pictures speak for themselves, there is not much to add 🙂
