The mansion was originally built as a summer home for Pedro de Osma y Gildemeister, a prominent Peruvian businessman and politician.
The collection includes significant examples of 'Cusco School' painting, known for its distinctive blend of European technique and Andean iconography.
The estate's gardens feature over 20,000 square meters of greenery, retaining original landscape design elements from the early 1900s.
The museum holds one of the most comprehensive private collections of viceregal religious sculpture in Peru.
The architectural style of the main house is heavily influenced by the French neoclassicism popular among the Lima elite at the turn of the century.
The Museo Pedro de Osma is housed in a former early 20th-century summer residence, the Casa de Pedro de Osma, located in the Barranco district. The museum preserves and exhibits a private collection of viceregal Peruvian art dating from the 16th to the 18th century. The collection features diverse media including paintings, sculpture, silverwork, and furniture from the Cusco, Ayacucho, and Lima schools. The museum building itself is an example of Belle Époque architecture characterized by ornate facades and gardens. Visitors can observe the transition of artistic styles influenced by both European traditions and indigenous Andean perspectives. The site is managed by the Pedro and Angélica de Osma Gildemeister Foundation. It functions as a specialized center for the research and preservation of colonial-era cultural heritage.
