Sereď (Slovak pronunciation: [ˈserec]; Hungarian: Szered [ˈsɛrɛd]) is a town in southern Slovakia near Trnava, on the right bank of the Váh River on the Danubian Lowland.

Sereď lies at an altitude of 129 metres (423 ft) above sea level and covers an area of 30.454 square kilometres (11.8 sq mi).

In the Middle Ages, it lay on the trade route called "Bohemian Road" which ran from Buda to Prague on the right bank of the Váh river.

Sered had also been a large raft port and an important waterway until 1943 when a dam was built on the river Váh at Nosice.

Sereď was the site of one of three labour camps for Jews established in the first Slovak Republic, a Nazi client state during World War II.

Before the work was completed, the Slovak authorities had utilised the camp as a detention centre for Jews and as a staging ground for deportation to Poland.

Shortly thereafter, however, the Germans regained control over western Slovakia, and the camp was enlarged under the command of Alois Brunner.

A factory producing a wide range of garden concrete paving stones started its business here, too.

[5] The historically most important building is the Esterházy manor-house (castle) which is located on the site of the once famous medieval water-castle of Sempte.

When the former church burned down on 2 August 1777, the Esterhazy family decided to build a new one and they moved there the two renaissance tomb-stones with relief of anti-Turkish warriors.

It is decorated with valuable paintings depicting views of St. Petersburg brought by Nikolaus Esterházy from his diplomatic mission in 1771.
