Hard to miss and easy to linger in, this L-shaped square is basically an open-air museum. Grab a seat at a café (yes, it’s pricey, but the people-watching is worth every euro), and you’ve got front-row views of Palazzo Vecchio, the Fountain of Neptune, and the statue of Cosimo I on horseback. Just off to the side is the Loggia dei Lanzi, packed with Renaissance sculptures—all free to see, no ticket needed. Early mornings or late evenings are quieter if you want to take it all in without the daytime crowds.

This is an award winning museum that houses two permanent exhibitions, telling the stories of the City of Derry and of an Armada shipwreck found off the coast of Donegal in 1971 through a range of displays and interactive exhibits. The top floor provides panoramic open air views of the city and the River Foyle.

The Guildhall, located in Derry's main city square, is one of the town's iconic landmarks. Built in 1890, it's been beautifully restored since, and welcomes visitors to its elegant insides where members of the Derry City Council still regularly gather.

The Leaning Tower of Pisa is one of Italy’s (and the world’s) most recognisable landmarks—but the tilt that made it famous wasn’t part of the plan. Construction started in the 12th century, and the soft ground caused it to lean almost from the beginning. Up close, it’s oddly striking, almost like a lopsided wedding cake, and yes, you can still climb it.
