The Feira da Ladra is a flea market laid out on the ground of Campo de Santa Clara, the long sloping square between the National Pantheon and the monastery of São Vicente. Most of what is for sale comes out of Lisbon flats: cutlery, spectacles, army badges, records, saints, mismatched crockery, old door keys, spread on blankets by people who are not traders in any organised sense. There are antique tables too, and loose azulejos prised off buildings. Prices are whatever you agree.
The name means thieves' fair, and a market under it is recorded in the city from the 1200s; it moved several times before settling here in 1882. It is held on Tuesdays and Saturdays. Early in the morning the dealers are still going through the goods and the best things are still on the ground. The organised tables pack up first, and the blanket sellers — the more interesting half — end up with the square to themselves.
