The name Riesa is derived from Slavic Riezowe. This name, romanised as "Rezoa", appears first in October 1119 in a document from Pope Callixtus II.
The world's first 110 kV power line was installed between Riesa and Lauchhammer in 1912. Between 1952 and 1994, Riesa was the seat of a district.
The town grew from the start of the 20th century due to industrialisation. The population declined after German Reunification in 1989. The local steel works shut and the population fell from 52,000 to 31,000.
Riesa has a 25 m tall, 234 tonne, cast-iron (GGG 40) sculpture of an oak trunk, named Elbquelle, which means source of the Elbe, by Jörg Immendorff, erected in 1999. Local folk call the sculpture by many other names, most notably "Rostige Eiche", which means "Rusty Oak".
Riesa is well known locally for its pasta, which is produced at Teigwaren Riesa GmbH. Another symbol of Riesa are the Riesaer Zündhölzer, the matches which were traditionally manufactured there.
The steel production in Riesa is also well known.
Riesa has a football club, BSG Stahl Riesa. The club's crest is blue and white, as are the club colours. They play now in the Landesliga Sachsen (6th tier).
