The Monasterio de los Jerónimos de Santa María de Belém is a Gothic Manueline marvel. The highlight is its three leveled inner cloister. Without doubt, it is the most beautiful cloister that I have ever seen in my life. It's great to get on the top floor and see how the view changes depending on the height. There is also a small gazebo a little higher up which is accessed from the cloister's top floor - it has stunning views. The cloister is the work of Joao de Castlho from 1544. The same artist also has beautiful reliefs in the south porch. Inside, the nave is huge. In Santa Maria church, the vault is supported by startlingly thin octagonal columns.
