The National Pantheon took two hundred and eighty-four years to finish, and Portuguese picked up a phrase for any job that never ends: obras de Santa Engrácia, the works of Santa Engrácia. The parish laid its first stone in 1682, the money ran out, and it ran out again every time work restarted, so the walls stood open to the sky for generations. The dome was finally closed in 1966. From the terrace around it, eighty metres up, you look over the Alfama roofs and the river.
By then the building had a second purpose. In 1916 the young republic declared it the National Pantheon, a place to bury the people it chose rather than the kings it had inherited. Inside are Almeida Garrett, several presidents, the fado singer Amália Rodrigues and the footballer Eusébio. Around the walls stand monuments that hold nobody at all, raised for men who were already buried somewhere else.
