Offenbach am Main sits directly across the river from Frankfurt and is very much its own city despite being swallowed by the same metropolitan sprawl. It has the highest proportion of foreign residents of any large German city — over a third of its population — which gives it a genuinely multicultural character, particularly visible in its food scene and street life.
The city's industrial past centred on leather goods, and the Deutsches Ledermuseum (German Leather Museum) remains one of the more unusual specialist museums in Germany. Design has stayed part of the city's identity: the Klingspor Museum holds an excellent collection of book art and typography. Along the riverfront, old factories are slowly converting into studios and offices, and the Mainuferpark offers a pleasant walk with Frankfurt's skyline across the water.
