For travelers to Erfurt, a visit to the 6,000-square meter egapark and to the Old Synagogue, central Europe's oldest surviving synagogue, are not to be missed. Both sites are also largely barrier-free. The permanent exhibition on the life of Martin Luther at St. Augustine's Monastery is also accessible to disabled visitors. For the past 10 years, Erfurt's city planners have been working to make these and other local attractions barrier-free and therefore accessible to all. The city also offers opportunities for visitors with vision or hearing impairments to experience what Erfurt has to offer, including sightseeing tours in sign language, and a large model of the historic city center labeled in Braille.
