The Pedro de Osma Museum exhibits Peruvian artistic pieces from the fifth to the eighteenth century. The art works from Ancient Peru correspond to the geographic area of the South Andes and belong to a private collection from Cuzco. The Tiahuanaco and Inca cultures were developed on this territory. The pieces from the viceregal period consist of paintings, sculptures, furniture and silver works that belonged to the Pedro de Osma Gildemeister collection (1901-1967). Paintings from the eighteenth century Cuzco school are among the highlighted pieces of the viceregal art collection. This valuable artistic heritage is currently exhibited in the Pedro de Osma house, built in 1906 by his father, the politician and notary Pedro de Osma y Pardo.

To achieve the museum objetives towards society the institution aims to:

  • Promote, investigate and preserve the collection of Pedro de Osma and his emblematic home built at the turn of the twentieth century,  located in the heart of Barranco.
  • Incentive the appreciation and study of viceregal period and Ancient Peru, fundamental historical eras in the creation of Peruvian identity.
  • Cultivate artistic talent and creative dialogues among local and global communities in a didactic, accesible and inspiring setting.


The Pedro de Osma Museum owes its incipience to its namesake, the collector Pedro de Osma Gildemeister, who bought, protected and exhibited Peruvian viceregal artworks.

For most of his life, until his death in 1967, he collected art made in Peru during the fifteenth through the eighteenth centuries, objects such as: paintings, sculptures, altar decorations, silverwork, sculptures in Huamanga stone, and furniture – originating from diverse centers of traditional Andean artistic creation – especially Cusco and Ayacucho. He exhibited these works in the various rooms of his home, with no pretension of claiming the space as a museum. He took great pride in his collection and strove to share it with others. He often presented and explained the works to guests.

After the death of Pedro de Osma, the Pedro y Angelica de Osma Gildemeister Foundation was formed in order to conserve and exhibit the collection of Pedro for the public. In the year 1988 the Pedro de Osma Museum opened its doors for private groups with reservations, and in 1996 the Museum began operating on a continual schedule, six days a week.

The Museum, in its mission to conserve the patrimony of Peru dating to the viceregal era, educate international visitors and Peruvians on viceregal visual culture, and contribute to academic investigations in the field of viceregal art history, provides a venue in which to strengthen the Peruvian cultural identity and appreciate viceregal culture.
