The canalisation of the River Elde (1798–1803 and 1831–1837) and the construction of the Bolter Canal (1831–1837) resulted in an economic boom in the town. In 1839 a vocational school was founded. In 1845 the first public baths opened on the Müritz. In 1862 the Birkenstädt Brewery was founded in present-day "Müritzstraße" by the town harbour; the brewery closed again in 1920. In 1869 the grammar school ("Gymnasium") opened, initially as a progymnasium, (today it is the Richard Wossidlo Grammar School). In 1848/49 the country road ("Chaussee") from Malchow via Waren to Neubrandenburg was built and, with its connexion to the Waren–Malchin railway in 1879, Waren developed into a transport hub. In 1885 the Mecklenburg Southern Railway from Parchim via Waren to Neubrandenburg was opened and, in 1886, the Lloyd Railway from Neustrelitz via Waren to Rostock followed suit.
