The Neue Welt is a sub-district of Münchenstein, in the canton of Basel-Country in Switzerland.
The geographical area called the Neue Welt (new world) evolved in the 17th century as the industry started establishing itself around the upper end of the "St. Alban-Teich". This is a canal, artificially constructed by the Basler Kloster St. Alban during the 12th century, so as to bring water and water power to the industry in Basel. Later, during the years 1624–25, the canal was prolonged through Brüglingen towards the Birs waterfall in Münchenstein and from here the water is diverged.
The Neue Welt is the northernmost district of Münchenstein. Neue Welt lies along the western bank of the river Birs. To its east it borders on the municipality of Muttenz and to the west it borders on Dreispitz, a business and economic service neighbourhood that lies half in Basel and in Münchenstein. To the north Neue Welt borders on St. Jakob an der Birs (now part of Basel), this was the site of the famous Battle of St. Jakob an der Birs, on 26 August 1444.
The hammer mill (Hammerschmiede), built in 1660 by Ludwig Krug, is the oldest building situated on the banks of the canal. In 1822 the hammer mill was refurbished as a cotton-spinning mill by Felix Sarasin (1771–1839). The hammer mill was restored and completely refurbished in 1970 by the Chr.Merianische Stiftung and was placed under monument conservation a year later.
The Villa Merian, with its English Garden, stands upon the elevated plain directly above the watermill and the canal. The Baroque manor house was built in 1711 by Alexander Löffler. In 1801 the manor was rebuilt in early Classicism style and approximately ten years later the manor and its properties were acquired by Christoph Merian-Hoffmann who gave the estate to his son Christoph Merian as wedding present. The Villa Merian is now a coffee house.
A late Gothic mill is situated directly below the Villa Merian. The mill is first mentioned in a deed dated 1259. The Operation of the mill continued until 1925. Since 1966 the watermill building is now being used as the Watermill Museum Brüglingen.
