The Jerónimos Monastery is a National Monument and was classified as a UNESCO World Heritage Site in 1983. Step onto these significant grounds for a snoop around and skip the line inside, where you can explore the whole place and ponder its homage to Portuguese identity and culture. Dont forget to look up at the psychedelic ceilings!, Take a seat in the 16th-century cloister, peer inside the former monks’ refectory, and imagine what it was like to browse a book by candlelight in the former library. Not only is this a thrilling trip through Lisbons history, the views over the Tagus River from the grounds are exceptional.
