• Around 40 peacocks roam the gardens and sleep in the stone pines; staff ask visitors not to feed them human food
• Two guided tours included: the hour-long castle tour is the only way into the archaeological site, and the camera obscura tour runs from 11am, weather permitting
• Walls and towers close early, at 5:30pm in winter and between 6pm and 9pm in summer depending on daylight, so climb them first

Castelo de São Jorge is a Moorish-era fortress on the city's highest hill, with walls and towers to walk and views over the rooftops to the Tagus. Around 40 peacocks roam the gardens and nest in the stone pines.

The ticket includes a guided tour of the archaeological site, with the remains of 11th-century Moorish houses, and a camera obscura in Ulysses Tower that projects live views of the city.
