Vratislavice nad Nisou (German: Maffersdorf) is a self-governing borough of the city of Liberec in the Czech Republic.
The settlement of "Wratislawicz" was established, it is thought, in the 13th century by Bohemian colonists on the left bank of the river Nisa.
A carpet-making factory founded by Ignaz Ginzkey (and developed by his son Willy) achieved world renown.
In 1901 both villages were merged into one market town (population 6,234 by 1934), and Czech inhabitants started to use currently known name Vratislavice.
Nowadays, the streetcar route is operated by the local transportation company Dopravní podnik města Liberce.
After the dissolution of the Communist Party rule during the Velvet Revolution, some companies found the transition into the free-market economy very difficult.
During a two-year dormancy the company was bought by the Hols firm, and with help of many friends of Maffersdorfer beer the brewery was put back into operation in summer of 2004, trading under the name of Konrad.
