Piazza del Mercato

About

Piazza del Mercato is one of Siena's most iconic public squares, situated in the heart of the medieval city center just behind the Palazzo Pubblico. Historically the site of the city's livestock market, the square has evolved into a vibrant public space that today welcomes visitors from around the world. The square's most recognizable feature is the 1884 covered market, known as the "Tartarugone" or "Tortoise" for its thirty‑two octagonal brick pillars and airy wooden roof. Designed by engineer Giuseppe Cantucci, this architectural gem draws parallels to Siena's historic palazzo and adds a distinctive medieval flair to the ambience of the square. After the market ceased operations in 1954 when the trading moved to Viale XXV Aprile, Piazza del Mercato has continued to thrive as a bustling plaza that hosts festivals, markets, and cultural events while overlooking the Tuscan valley that lies beneath. The square is open to the public free of charge, with typical visiting hours from 10:00 am to 4:00 pm, making it an ideal, no‑cost destination for anyone wishing to experience authentic Siena life.
