Goyeneche Palace, Arequipa, Colonial palace in central Arequipa, Peru.

Goyeneche Palace is a two-storey manorial house at the corner of La Merced and Palacio Viejo streets, built of sillar, Arequipa's white volcanic stone. Its façade carries a full-width horizontal balcony with wrought-iron railings and the shield of José Sebastián de Goyeneche. Inside are ample patios, a black stone fountain in the main courtyard, vaulted ceilings, colonial doors and windows, and a spiral sillar staircase to the upper floor.

The site was first built on in 1558, when Bernardino de Ávila erected a mansion later called the Palacio Viejo. The architect Gaspar Báez built the present house in the 18th century, but the 1782 earthquake left it near collapse. Juan de Goyeneche y Aguerrevere bought and restored it, and in 1837 Bishop Goyeneche commissioned Lucas Poblete to rebuild it; the mansion was finished in 1840.

The name comes from the Goyeneche family, who acquired the damaged house and restored it as their residence; Bishop José Sebastián de Goyeneche lived here until 1858, when he became Archbishop of Lima. The family gave the mansion the city's first private library and a documentary archive on the Emancipation era, and the façade bears the bishop's shield.

The palace stands at the corner of Calle de la Merced and Calle del Palacio Viejo, a short walk from Arequipa's main square. It now houses the Arequipa branch of the Banco Central de Reserva del Perú, so access follows the bank's museum arrangements rather than those of a private house. The entrance portico and zaguán were built tall enough for a mounted man to pass with an upright French lance.

The main patio holds a fountain carved from black stone, a detail often missed by visitors heading straight for the staircase. The house also kept the first private library in Arequipa and a documentary archive focused on the Emancipation era, assembled by Bishop Goyeneche before he left for Lima in 1858.
