The Basílica da Estrela (Estrela Basilica) is an impressive neoclassical (with a hint of baroque) domed church in the Estrela district of Lisbon. The style is somewhat similar to the National Palace in Mafra and so is its reason for being.
Like her father, Queen Maria I of Portugal decided to have a massive church built as thanks for the birth of her first child. Work began on the basilica in 1779, when the Prince was already 18. The story became a tragedy though,with Prince José dying of smallpox before the church was completed in 1790. His tomb can be seen in Royal Pantheon of the House of Braganza in the Alfama.
