Mönsterås harbour is a quiet former shipping harbour for mainly agricultural products. Among other things, here is a silo, a warehouse and a small steam powered harbour crane from 1922. Today, Mönsterås harbour is not used for commercial shipping, but there are some older wooden ships that remind you of days gone by. One of these is the galleass Hvitfeldt, built 1903 in Esbjerg, which was sailed as a trawler in the North Sea. Her home port was Esbjerg until she was sold to Sweden in 1969. After a couple of years in Malmö, Stockholm and Oskarshamn, Mönsterås is now her home port.
Close to the harbour is the church outside of which there is a memorial over the dean Jacob Wallenberg, the author of the 18th century novel "Min son på galejan". Wallenberg's rectory Lilla Forsa outside the community is also preserved.
