Piazza Castello

Turin's monumental heart

Piazza Castello is Turin's grand centrepiece and the natural starting point for a first walk around the city. The sweeping, arcaded square took shape from the 16th century onwards as the stage for the House of Savoy's ducal and later royal power. From here, the city centre's main axes fan out — above all the elegant Via Roma towards Piazza San Carlo and the arcaded Via Po down to the river. The square itself is open to everyone and costs nothing to enter; you only pay for the museums around it.

The buildings around the square

Several major sights cluster around Piazza Castello, and nearly all of them can be combined in a single day:

• Palazzo Reale – the former royal palace of the House of Savoy and entrance to the Musei Reali, with state rooms, an armoury, a picture gallery and Guarini's Shroud Chapel
• Palazzo Madama – part medieval castle, part Roman city gate, fronted by Filippo Juvarra's baroque facade; home to the Museo Civico d'Arte Antica
• Teatro Regio – the royal opera house, whose striking modern interior can only be seen on a guided tour or during a performance
• Real Chiesa di San Lorenzo – the elegant baroque church with Guarino Guarini's intricately interlocking dome, free to enter

The famous Turin arcades run all around the square — a signature feature of the city, with around 18 kilometres of covered walkways that make strolling possible whatever the weather.

What to expect, and whether it's worth it

Piazza Castello is less a destination in its own right than the hinge where Turin's centre comes together — and that's exactly what makes it essential. Allow 30 to 60 minutes to circle the square, take in the facades and decide which palaces you want to see inside. It's most atmospheric at blue hour: once the floodlighting comes on after sunset, Palazzo Madama and the arcade arches stand out beautifully against the evening sky. If you're short on time, use the square purely to get your bearings; with more time to spare, build a half-day around it in the Centro Storico.

Visiting and practicalities

The square itself is open at all times; only major events bring temporary closures. The buildings around it keep their own hours: Palazzo Reale/Musei Reali Thursday to Tuesday 9:00–19:00 (closed Wednesdays, full price €15), Palazzo Madama Monday and Wednesday to Sunday 10:00–18:00 (closed Tuesdays, full price €10), and San Lorenzo on weekdays 8:30–12:00 and 15:30–18:00, afternoons only on public holidays — visits aren't possible during Mass. The Teatro Regio can be admired from outside for free; the only way to see inside is the "Regio dietro le quinte" guided tour, held on selected weekend dates (€10, €5 under 18).

Right on the square, on the corner of Via Garibaldi, is the official tourist information office of Turismo Torino e Provincia (Mon–Thu 9:00–13:00 and 14:00–18:00, Fri–Sun 9:00–18:00) — a good first stop for maps and tickets.

Getting there and connections

Tram line 4 and numerous bus routes (including 11, 15, 55, 57) serve Piazza Castello, with nearby tram 13 adding further options. The square is an easy walk from both main train stations, Porta Nuova and Porta Susa. A dedicated metro stop is only planned once Linea 2, still under construction, opens, and it won't be running in 2026. If you're driving, the Parcheggio Roma–San Carlo–Castello (802 spaces, access from the corner of Via Viotti) is open 24 hours. For more on getting into the city, see the getting there guide.

The square makes an ideal starting point for exploring on foot: from here, the Cathedral and the Shroud, the Quadrilatero Romano and, via Via Po, the riverside along the Po are all a short walk away.
