Due Torri (Two Towers: Asinelli and Garisenda), Bologna (must see)

Dominating the scene at Piazza di Porta Ravegnana, where the main gate of the Roman walls once stood, are the iconic Two Towers, emblematic of Bologna's medieval past when the city boasted around 120 such structures. Dating back to the 12th century, these likely served as both lookout points and symbols of prestige. Legend has it that the Asinelli and Garisenda families, engaged in a fierce competition to erect the tallest and most magnificent tower in the city.

For a taste of history and panoramic vistas over the terracotta rooftops, brave the ascent to the top of the Asinelli Tower, rising over 97 meters (318 feet) high. Though the climb is steep, navigating a narrow spiral staircase of nearly 500 steps, the reward is well worth the effort. From the summit, you can spot other surviving medieval towers and, weather permitting, catch a glimpse of the Alpine foothills beyond Verona. Like many of Bologna's towers, both the Two Towers have a noticeable tilt: Garisenda tilts 3.33 meters (11 feet) northeast, while Asinelli leans 2.23 meters (7.3 feet) westward. Originally reaching 60 meters (197 feet), Garisenda was truncated by 12 meters (39 feet) in the mid-14th century due to unstable foundations; however, from certain angles, the two towers appear to be of equal height. Dante, who briefly sojourned in Bologna during his exile from Florence, famously referenced the leaning tower in "The Inferno" (before its reduction), likening it to the bent figure of Antaeus, the giant son of Poseidon, trapped in ice at the depths of hell.

Beneath the towers, yet not overshadowed, stands the 17th-century Saint Bartholomew's Church, featuring a Renaissance portico. Inside, seek out Francesco Albani's "Annunciation" in the fourth chapel of the south aisle, and Guido Reni's small "Madonna with Child" in the north transept. On the square's north side, the abrupt appearance of a starkly modern office building sparked controversy in the 1950s.
