The Trachten- und Heitmatmuseum is a museum about urban history, viticulture (wine production), Büttnerhandwerk (making butter by hand), and the guilds. Closed when I visited the city. Open Easter to October on Saturday, Sunday, and festival days from 14:30 (2:30pm) to 16:30 (4:30 pm). The museum is in a Schlosschen built in the 1300s.
Look at the page about Flooding in my warning section.
Address: Brückenstr. 26, 97199 Ochsenfurt
Alte Brucke = old bridge, usually the first one built in the town.
The Alte Mainbrucke was originally built around 1250 and rebuilt between 1512-1520. In May 2007 the bridge had been damaged. I do not know if/when the city is going to rebuild.
A few kilometres along the main road (or railway) east of Ochsenfurt is Marktbreit. This extremely pretty town has a museum, 'castle', town walls and a pretty church (you can climb the tower here). Next to the river is an old crane, very similar to the Alter Kranen in Wurzburg. The town also boasts the second oldest hotel in Bavaria (they don't tell you the location of the oldest!). And the town is the birthplace of Alois Alzheimer (in 1864), who gave his name to Alzheimer's Disease. And my neice goes to school here ;-)
Tourist Information Office close to the main road and main town gate, on Mainstrasse. Closed Mondays.
