This Neoclassical and Baroque basilica, dedicated to the Sacred Heart of Jesus, was built in the late 1700s by Queen Maria I in fulfilment of a vow. The Queen is entombed in the right transept. Among the artworks is a nativity scene made up of over 500 cork and terracotta figures by Joaquim Machado de Castro.

The Estrela Basilica (Portuguese: Basílica da Estrela [iʃˈtɾelɐ]) or the Royal Basilica and Convent of the Most Sacred Heart of Jesus (Portuguese: Real Basílica e Convento do Santíssimo Coração de Jesus), is a minor basilica and ancient carmelite convent in Lisbon, Portugal.

Ordered built by Queen Maria I of Portugal as the fulfilment of a vow, the Basilica is not only a product of the Queen's particularly fervent devotion to the Sacred Heart of Jesus, but remains the most important architectural endeavour of her reign. The Estrela Basilica was the first church in the world dedicated to the Sacred Heart of Jesus.
