Jardim da Estrela
Praça da Estrela, Estrela
Enter through the main gate. Walk past the bandstand, find a bench near the pond. Lisbon's first romantic garden when it opened in 1842 — a very Victorian bit of engineering for people who needed somewhere quiet to fall out with themselves. Best in the early morning, if you're the type.
The ducks won't give you space. The teenagers won't give you seats. The grandmothers and the dog-walkers will, eventually.
If you stopped improving for this hour, what would you do instead?
