Teatro Comunale dei Rinnovati, Baroque theatre in Palazzo Pubblico, Siena, Italy.

The Teatro dei Rinnovati sits within the Palazzo Pubblico and displays a classical stage layout with four tiers of boxes arranged in a U-shape around the main stage. The auditorium holds about 549 seats, allowing good sightlines from all positions to the performance space.

The Sala del Consiglio, built in the 14th century behind the Palazzo Pubblico, hosted celebrations for Charles V in 1536 and was fitted with a stage and gallery in 1560 by Bartolomeo Neroni, called Il Riccio. After the Accademia dei Filomati and then the Intronati ran it, the hall was rebuilt in 1647 by Carlo Fontana; the U-shaped house with 107 boxes opened in 1670 with L'Argia. Fires in 1742 and 1751 led to the bell-shaped plan with 88 boxes by Antonio Galli da Bibbiena, reopened in July 1753 with Tito Manlio.

The theatre takes its name from the Accademia dei Rinnovati, which bought it in 1800 from the Intronati and raised the roof. Its season runs mainly in winter, while in August it hosts the Settimana Musicale Chigiana. The 1753 hall keeps 88 boxes, including the barcacce and the boxes of the widows.

The theatre is reached through the Cortile del Podestà, entered from Piazza del Campo; the auditorium lies behind the Sala del Consiglio on the rear side of the Palazzo Pubblico. The 88 boxes, including the barcacce and the widows' boxes, sit on four tiers, so check the tier number on your ticket before climbing.

The 1753 rebuild by Antonio Galli da Bibbiena gave the theatre its bell-shaped plan with 88 boxes, including the so-called barcacce and the boxes reserved for widows, spread over four tiers. A double row of giant Corinthian columns forms the proscenium separating the hall from the stage.
