Jardins do Palácio De Cristal
Although there's no longer an actual crystal palace here (the grand original building, built to host the city's 1865 International Exhibition, fell into disrepair and was demolished in 1952 to make room for the somewhat unsightly sports stadium dubbed "the UFO" by locals), the Crystal Palace Gardens remain a lovely place for a stroll in the shade. With ornate fountains and statues, strolling peacocks, hidden chapels, rose gardens, and views over the Douro, it's a romantic spot beloved of both locals and out-of-towners.
