Rock carvings at �skollen and Austad are 6000 to 7000 years old, and are the first signs of human activity in the area. The largest rock carving at �skollen depicts a moose.
Drammen originally consisted of three small seaports: Bragernes (on the northern side of the Drammenselva river) and Str�ms� and Tangen (both on the southern side of the river). For trade purposes, small seaports were placed under market towns. Despite their geographical proximity, Bragernes was placed under Christiania and Str�ms� under T�nsberg. For this reason, cooperation between the adjacent seaport towns was almost impossible.
In 1662, a merger was proposed to unite Str�ms� and Bragernes to form a market town with the name Frederiks str�m. The proposal was rejected by Frederick III of Denmark. Bragernes received limited market town rights in 1715, and merged with Str�ms� to gain status as a single city on 19 June 1811.

Its unique geographical location made the city a centre for seafaring, shipbuilding, log driving, timber trade, and (since the 19th century) paper and pulp industries. During the 1960s most of the pulp and paper factories along the Drammenselva were closed down.
Large parts of the city were ruined in the great fire of 12�13 July 1866, which led to the reconstruction of the city centre, including the characteristic town square and Bragernes church.
In 1909, Drammen got the first trolleybus system in Scandinavia, the Drammen trolleybus. The lines ran until 1967. For many years the centre of Drammen suffered from heavy traffic, but in 1970 the European route E18 bridge helped somewhat, and in 1999 the opening of the Bragernes tunnel diverted much of the traffic away from the centre of the city. In recent years, the city centre has seen significant regeneration, with the introduction of new housing, shopping facilities,
