Höchst (German pronunciation: [ˈhøːçst])[2] is a neighbourhood and market town in the Ortsbezirk of Frankfurt-West in Frankfurt am Main, Germany.

Höchst is situated 10 kilometres (6.2 mi) west of Frankfurt city centre, on the north bank of the Main at the confluence with the River Nidda.

In a charter dated 12 January 1356, Charles IV gave additional privileges to Höchst including the right to hold markets every Tuesday.

[11] On 22 June 1622, during the Thirty Years' War, the Battle of Höchst saw a Catholic League and Spanish Empire armies defeat a Protestant force.

[citation needed] The Hoechst AG was headquartered in Höchst until in 1999, when the company was merged with the French Rhône-Poulenc S.A. and became Aventis[17] which, after another merger, became Sanofi-Aventis.
