The TT Circuit Assen is a motorsport race track built in 1955 and located in Assen, Netherlands. Host of the Dutch TT race, it is considered "The Cathedral" of motorcycling by the fans. It has a capacity of 100,000 spectators, including 60,000 seats. Lately it has become a venue for concerts as heavy metal legends Iron Maiden announced that they would perform at the circuit making them the first band to hold a concert at the venue.


The original Assen track was first used for the 1925 Dutch TT (Tourist Trophy) race, held on country roads through the villages of Borger, Schoonloo and Grolloo, and organized by the "Motorclub Assen en Omstreken". The brick-paved track had a length of convert|17.75|mi|km|2. The winner was Piet van Wijngaarden on a 500 cc Norton with an average speed of convert|91.4|km/h|mi/h|1|sp=us.

The years afterwards the Dutch TT was held on a road circuit through de Haar, Barteldbocht (near Assen), Oude Tol, Hooghalen, Laaghalen and Laaghalerveen.

In 1951 the Italian Umberto Masetti took the record on a 500 cc Gilera with an average speed of convert|100.88|mi/h|km/h|2. In 1954, Geoff Duke of Great Britain reached convert|106.06|mi/h|km/h|2. The circuit remained unchanged until 1955, when a whole new circuit was built close to the site of the original, but less than a third of the length — and much more like a modern road racing circuit.

The circuit was fundamentally redesigned again in 2006 — the so called A-Style Assen TT Circuit. All alterations aside, only one section of the circuit is original; the finish line never moved.

Current racetrack

The current Assen race track was built in 1955, and initially had a length of convert|7705|m|mi|3|sp=us. The current track has a length of convert|4555|m|mi|3|sp=us. The longest straight is convert|560|m|mi|3|sp=us. The curves in Assen were traditionally banked and the surface is extremely grippy, so the riders were able to drive much faster on the course than other circuits. Today these sloped or curved bends have been modified due to safety issues.


On July 6, 2004 the organization announced plans for an amusements park on the northwards of the track. In 2006 the northern loop was removed and the length was shortened to 4,555 meters. The new centre is scheduled to be visited by 300,000 people. The total investment is c. € 85 million.


*The TT Circuit is the only circuit on the world championship calendar that was already on the calendar when the series started in 1949.
*The Dutch TT is always held on last Saturday of June.
*It is the only roadracing circuit in the series specifically designed for motorcycle racing. However, Champ Car made its Dutch debut in 2007 at Assen.
*The track layout makes it a very technical, twisty circuit with little room for error, although track alterations carried out over the years paradoxically make it a 'safe' circuit. Further alterations were carried out in 2007 for Champ Car.
*The curves are banked and the surface is extremely grippy, even in wet conditions.
*Iron Maiden are going to be the first band to play a concert there, as part of their Somewhere Back In Time World Tour 2008 on 16th August.
