Pisa.

Pisa's cathedral square brings the Cathedral, Baptistery, Leaning Tower and Camposanto into one striking ensemble. Come for the relationship between the four monuments, then decide which interiors deserve your time.

The white marble buildings stand apart on a broad green lawn, so their different shapes are easy to compare: the Cathedral's long body, the Baptistery's dome, the Tower's stacked arcades and the Camposanto's enclosing wall. The operator presents them as an allegory of life, from baptism to burial, giving the square more to offer than a tower photograph.

Piazza del Duomo is the square's formal name; Piazza dei Miracoli is the name many visitors know. Its monuments grew over centuries rather than from one building campaign. The Cathedral began in the eleventh century and established a Pisan Romanesque language of marble surfaces and open galleries. The Baptistery followed, its lower rounded arches and upper pointed arches recording a shift toward Gothic design. The Camposanto came last, giving the square a monumental burial ground. Seen together, the four buildings tell a religious sequence: baptism, worship, the call of the bells and burial. Their separation is part of the experience. From one position on the lawn, you can read the distinct purpose of each building and notice how later builders responded to what was already standing.

• The Cathedral, Baptistery, Tower and Camposanto form a single ensemble across the lawn.
• The Tower is the Cathedral's bell tower, set behind the church rather than attached to it.
• The Camposanto closes the northern edge of the square with a long, restrained wall.

Walk the square first to see how the four monuments relate before choosing interiors.
