Palazzo Ruschi, palace with neoclassical lemon house in Pisa, Italy

Palazzo Ruschi is a palace in Pisa's San Francesco district, built on ancient structures with massive columns still visible on the ground floor. Its present form dates to the 16th century, with a 17th-century facade and an entrance staircase designed by Ignazio Pellegrini. The interior features frescoes by Giovanni Battista Tempesti, including the Room of Allegories with the Four Elements. The garden contains a neoclassical lemon house built between 1828 and 1835, measuring 28 by 17 metres.

The palace stands on very old structures, with massive columns still visible on the ground floor. Its present form dates to the 16th century, with additions over the following three centuries; the facade is 17th-century, and Ignazio Pellegrini designed the entrance staircase. The Ruschi family lived here until the 1960s. On land bought in 1823, the lemon house was built between 1828 and 1835, facing south toward the palace.

The Ruschi family, of ancient Ghibelline nobility, lived in the palace until the 1960s. The garden belongs to the Pisan tradition of "orti Pisani": walled green spaces with fruit trees rather than purely ornamental grounds. Its layout moved from 17th-century formal symmetry toward the irregular spaces of English gardens, an early departure from Italian garden custom.

The palace occupies the block between Piazza San Francesco, Via San Francesco and Vicolo Ruschi, northeast of the Arno in Pisa's medieval centre. The garden is enclosed by high brick or stone walls, as is typical of Pisan private gardens, so it is not visible from the street. The lemon house stands at the north edge of the property, facing south toward the palace.

The lemon house, built between 1828 and 1835, measures 28 by 17 metres (476 square metres), making it the largest in Pisa and comparable in size to the palace it serves. It faces south towards the palace and was erected on land bought by Francesco Ruschi in 1823.
