Palazzo Salimbeni

Palazzo Salimbeni houses Monte dei Paschi di Siena, founded in 1472 and still the world's oldest operating bank. You can't go inside, but the 14th-century Gothic facade with its stone crenellations and arched windows makes this one of Siena's most striking medieval buildings. The real draw is how perfectly it anchors Piazza Salimbeni, creating what feels like a private courtyard in the heart of the city.

The square itself feels intimate and refined, flanked by two Renaissance palaces that complement the Gothic centerpiece beautifully. You'll find yourself naturally drawn to walk the perimeter, admiring how the three buildings create perfect architectural harmony. The statue of economist Sallustio Bandini sits right in the center, and locals often use the steps around it as an impromptu meeting spot.

Most guides oversell this as a major attraction when it's really a lovely 10-minute stop while exploring the centro. The morning light hits the stone facade beautifully, making photos much better than afternoon shots. Skip it if you're rushing between the Duomo and Piazza del Campo, but if you're wandering the medieval streets anyway, it's worth the short detour for the architecture and peaceful atmosphere.
