Palazzo Ranuzzi, Renaissance palace in Bologna, Italy

Palazzo Ranuzzi is a Baroque palace in central Bologna, also known as Palazzo Baciocchi or Palazzo Ruini. Its facade was built around 1582, possibly on a design attributed to Andrea Palladio, though local craftsmen carried out the work. Inside, a Rococo staircase with two elliptical ramps, built in 1695 by Giuseppe Antonio Torri and Giovanni Battista Piacentini, leads to the piano nobile, whose rooms are frescoed by painters including Marco Antonio Franceschini, Felice Giani and Pelagio Palagi.

Carlo Ruini commissioned construction in the late 1500s before the Ranuzzi family acquired the building in 1679. The family carried out major renovations over the following decades, which continued until 1822.

The palace is still called Baciocchi and Ruini after two of its owners. Felice Baciocchi, widower of Napoleon's sister Elisa, bought it in 1822 and had the buildings opposite demolished to create today's Piazza dei Tribunali. Since 1873 it has housed Bologna's judiciary, now the Court of Appeal.

The palace is the seat of Bologna's Court of Appeal and is a working courthouse, so the interiors are not open to tourists. Visitors can view the facade and the Rococo staircase from the entrance area, and the building faces Piazza dei Tribunali, created when Felice Baciocchi had the houses opposite demolished.

The palace's name changed with its owners: it was Palazzo Ruini until the family died out in 1634, then Palazzo Ranuzzi after the 1679 sale, and is also called Palazzo Baciocchi after Prince Felice Baciocchi, who bought it in 1822 and demolished buildings opposite to create today's Piazza dei Tribunali.
