Alvinc (Vințu de Jos, Vinț, Unterwinz or Winzendorf, in Saxon: Wints vor Wänts) is located in Transylvania, now Romania. It is famous for its fortified church and for the ruined Martinuzzi Palace, where Prior György (Fráter György) was murdered in 1551. It is situated 14 km southwest from Gyulafehérvár (Alba Iulia), on the left bank of the Maros River.

It was first mentioned in 1205 founded by Saxon settlers. It became an important strategic place in the 13th century because the salt was transported through Alvinc. The Fransciscanians built their church in 1300. The settlement became an oppidum in 1370 and had the right to hold markets. It is a civitas in 1430, together with Borberek.

There were 182 landholders in 1488 with a full length of the land. The Turks broke in 1438 and in 1442 and as a result of this many Saxons died. There was a major plague as well. Hungarian settlers took shelter in Alvinc during this time, along with southern-Slavic Catholic folks. The place was owned by Radu de la Afumați, Voivode of Wallachia between 1526-1529.

Alvinc changed several owners during the Dual Kingship of Hungary. Imre Balassa and István Majláth, and their friends were preparing their plot in Alvinc in 1539 which was soon revealed. Prior György got Alvinc in 1546 and he was murdered there on 17 December 1551 by the assassins of King Ferdinand I.

The Wallachians (Romanians) came there at the end of the 16th century, they lived in a separate part called Oláhvinc (1657). The last Saxon priest left Alvinc in 1590. Alvinc was the place where the Moldavian Voivode Aaron the Tyrant (Romanian: Aron Tiranul) was killed in 1597. Prince Gábor Bethlen had Hutterites (Anabaptists) settled there between 1621-23. The Tatars destroyed it in 1658. Catholic Bulgarians arrived in 1690 there.
