Portugal's parliament sits in a former Benedictine monastery built from 1598, rebuilt by Ventura Terra after a fire in 1896-1903. Anyone with ID can watch a plenary session from the public galleries, and across Rua de São Bento the Casa do Parlamento, opened for the 50th anniversary of the Carnation Revolution, explains how Portuguese democracy works.
