Many well-preserved half-timbered houses can be visited in the historical town center. Various parts of the medieval wall are preserved as well. The two gates, however, are not preserved, but two streets (
Steintor and
Leintor) are named after them. St. Mattäus Church was founded in 1457 and renovated by the famous architect
Georg Ludwig Friedrich Laves from 1856 to 1859. The church is famous for its medieval
winged altarpiece dating from 1415. The pulpit and the baptismal font were created in 1859 and the organ dates from 1869. The clock tower measures 55 metres in height. The ruin of Saint George Chapel, a small
gothic chapel with typical
pointed arches representing the style of the Middle Ages, can be visited in the north of Gronau outside of the historical town centre. Originally it was a part of a hospital which was demolished in 1960. The Town Hall dating from 1907 in the Market Place represents the style of
Gründerzeit. The monastery of
Dominican Order was founded in 1680. Its
aisleless church dates from 1715. Near the monastery a part of the medieval town wall with a
fortified tower built in the 14th century can be visited. The tower measuring ten metres in height got the nickname
Leaning Tower of Gronau. Unlike the other fortified towers in Gronau it was not demolished at the end of the 18th century, as it was used as a prison for a long time. The Jewish cemetery founded in 1819 can be visited in
Hoher Escher Street. 57 graves are preserved. The cemetery was used until 1934, devastated in 1938 and renovated in 1978. The former synagoge of Gronau, built around 1820, is still preserved in
Südstraße Strasse no. 14. As it is in a narrow lane surrounded by wooden half-timbered houses it was not set on fire in 1938 in the
Kristallnacht but transformed into a residential building. Unfortunately there is no conmemorative plaque fixed on the building. ==Infrastructure==
