If I were to build a fort, it would look like this

[LISBON] — High overlooking Lisboa, is the Castelo de São Jorge, one of the coolest forts I’ve seen. Lots of excellent shooting points, areas of properly dispersing hot oil and other general harassment.  It’s a great thing to do in the morning or sunset.  You can take the trolly up, or walk the zigzag streets. Excellent views of the red roofs of Lisbon.
