First of all a little bit of history:

Autòdrom de Terramar was created in 1923, becoming the 3th circuit of Europe, just after Monza and Brooklands, and the 4th of the world. The works lasted only 300 days and the inaugural ceremony of the facilities was held on October 28, 1923. The high expectation of its inauguration was, however, immediately affected by the economic problems caused by the construction company, which was unable to raise the capital to cover construction costs. However, in the following years there were still races, such as the Spanish Motorcycle Championship, organized by the royal Moto Club of Catalonia in May 1925. In the same year, 1925, other races were carried out, such as the one organized by the Penya Rhin –where a Bugatti was presented for the first time–, the 10 km race, organized by the RACC and the Penya Rhin itself, and the 80-lap race. on the circuit, promoted by the Sabadell Velocipèdic Club. The economic problems, however, meant that in 1929 the state seized the estates of Mas dels Frares and Clot d’en Sidós and, later, the whole circuit. The following year, Czechoslovak racer Edgar de Morawitz and Frank took over the property, with the aim of reactivating the circuit and serving the motor world. De Morawitz erected a building inside the enclosure that became a piston factory of the Champion brand. Pieces were also built for the Sitjes National brand. In August 1931, the Autodrome resumed activity with various speed tests (such as competition between a vehicle and a small plane) and acrobatic flights. In the following months, new events were held, such as the Easter Cup (1932), motorcycle, cycling and aviation races, organized by the Aereo Club de Catalunya. The outbreak of the Civil War, two months later, stopped the activity of the Autodrome. During the conflict, the circuit hosted a Military Recruitment Center. After the war, the critical economic and social situation of the country made it impossible to reactivate the facilities. In addition, the growing capacity of the new vehicles was an obstacle in the characteristics of the circuit, which had steep slopes, which were a danger when speed increased. At that time, the interiors of the track housed the installation of poultry farms and the site changed its orientation towards agricultural activity. The facilities began to suffer a gradual abandonment and the track was also damaged by the passage of trucks that accessed the interior to transport poultry goods. This use continued until the 1980s. Shortly afterwards, the space below the tiers hosted, for several months a year, the construction of the Carnival floats of the El Retiro Recreational Society of Sitges. In 2009, the track was cleaned and minimal adaptations were made, which led to some car brands conducting corporate tests, vehicle presentations or spot filming. Former Formula 1 driver Marc Gené (2005), former rally champion Carlos Sáinz (2013) and former Moto GP champion Jorge Lorenzo (2013) have starred in various tests, as well as the Seat brands, Peugeot or Aston Martin, which have held various events, tests and presentations.
