Lisbon’s castle is an excellent structure to explore, and often empty enough to relax, too. Walk out onto the ramparts for a longer visit, or keep it to the perimeter walls to save time. There are Roman ruins as you enter the actual castle itself, just to the right as you pass the portcullis. It’s easy to miss. Once you’re finished ogling the view and pretending to pour hot oil over the sides, go have a ginja (cherry liqueur) in a chocolate cup from the café and snap a few shots of the peacocks who are roaming around looking for the odd crumb.
