Claim: The Circuito Internacional de Vila Real, from its original 7.2km circuit, underwent several changes in its history and was closed to race from 1991 to 2007.
Evidence: Started as a 7.2km street circuit in 1931, it was later reduced to a 6.9 km version in the 1950s, which lasted until 1991, with small chances in some corner, chicanes introduction and start/finish line being moved forward. The circuit layout has suffered several changes through the times. After a deadly accident in 1991, no race would take place in this circuit until 2007, after a length reduction to a 4.6km long renovated layout.
