King Charles Albert chapel, Religious chapel in Gardens of the Palácio de Cristal, Portugal.

King Charles Albert Chapel is a small religious building with Romantic-style architecture set within the Palácio de Cristal Gardens. The structure displays stone walls and decorative features typical of 19th-century design.

Charles Albert, King of Sardinia, was defeated by the Austrians at Novara in 1849 and went into exile in Porto, where he died that same year at Quinta da Macieirinha. His half-sister, Princess Augusta de Montléart, had this cenotaph built near that estate; construction took nearly six years. The first Mass was celebrated in the chapel on 25 December 1861. It belonged to the House of Braganza until Queen Amélia, in exile, donated it to the Porto municipality in 1950.

The chapel bears the name of a Sardinian king who died in exile in Porto, reflecting the historical ties between the city and Italian royal families of the 1800s. Visitors can find here a quiet memorial space that speaks to this long-forgotten connection.

The chapel is accessible to visitors within the Palácio de Cristal Gardens and can be reached through multiple park entrances along Rua de Dom Manuel II. Walking through the gardens allows you to explore the grounds at your own pace and locate the building among the trees and landscaping.

The chapel holds three sculptures bought in Paris for its interior. Its first Mass was celebrated on 25 December 1861, and from 1950 it belonged to Porto City Council after Queen Amélia, in exile, donated it.
