Lucca, a relatively un-touristy Tuscan city, is known for its well-preserved Renaissance walls surrounding its historic center.

Broad tree-lined pathways along the tops of the 16th and 17th century ramparts are popular for biking and walking.

A walled stream runs down the center of the Via del Fosso. 

Lucca maintains the medieval-like layout of wandering streets, decorated archways and open plazas.

Lucca has three spectacular churches including the oldest from the 1100s, the Basilica of San Frediano.

The ring of buildings surrounding the Piazza del Antfitiatro follows the elliptical shape of the original Roman amphitheatre.

In Pisa, the medieval Borgo Stretto contains strolling arcades and the Lungarno, the avenues along the river Arno.

The main attraction in Pisa is the medieval Piazza del Duomo, a UNESCO World Heritage Site with its cathedral, baptistry and leaning bell tower.

Pisa's streets criss-cross dozens of piazzas, former market squares, which are lined with palaces and filled with statues.
 

Pisa contains 20 historic churches, several medieval palaces and various bridges across the Arno River.

Pisa is a hub of contemporary art, as seen in the numerous installations throughout the city, wonderfully juxtaposed against the historical architecture.
