Circuito di Ospedaletti

The Circuito di Ospedaletti commonly known as the Ospedaletti Circuit (official name: Autodromo di Ospedaletti) was a motor racing road course in the north-western coastal town of Ospedaletti (Liguria region of Italy), active from 1947 to 1972.

Circuit history
The Autodromo di Ospedaletti was the second designated venue for the San Remo Grand Prix from 1947 to 1951, after the original San Remo street circuit of the 1937 Grand Prix was no longer able to support the changing requirements of post-war Grand Prix racing.

The circuit opened in 1947 as a 2.625 km street circuit for the II Gran Premio di San Remo. In 1948 the circuit was reconfigured to a distance of 3.380 km prior to the third San Remo Grand Prix.
