The story that haunts this land
Schwerin reveals its first mysteries at the Gothic cathedral, erected between 1278 and 1416 with its 117.5-meter tower dominating the ducal city. Here in 1285 Duke Henry II of Mecklenburg was elected, founder of the lineage that would reign over these lands for more than six centuries. You discover in the nave the most impressive organ in Mecklenburg-Western Pomerania, installed in 1967 with its 91 registers, and the tomb of Duchess Helena of Mecklenburg, who died in 1638 after witnessing the birth of the castle's little guardian legend.
The Altes Palais transports you to the ducal golden age, this Baroque palace completed in 1819 under Grand Duke Friedrich Franz I according to architect Johann Friedrich Busse's plans. This former ducal residence of 10,000 m² housed the court until 1857, before serving as a Prussian barracks from 1884 to 1918. Listed as a historical monument in 1986, the palace testifies to the power of the Mecklenburg-Schwerin dynasty that made their capital one of northern Germany's most elegant courts.
The Paulshöher Damm offers you the perfect perspective on Schweriner Schloss, this 1.2 km historical dike reinforced in 1840 to protect the city from lake floods. Since 1850, this promenade has revealed the panoramic view of the Renaissance castle, rebuilt between 1843 and 1857 by William VIII of Mecklenburg-Schwerin. With its 36 meters height and 653 interior rooms, the castle has housed the Land parliament since 2006, perpetuating its role as seat of Mecklenburg power.
The Burggarten, created in 1860 by landscape architect Peter Joseph Lenné over 6 hectares, hides mythological figure statues from 1880 and has hosted outdoor concerts since 1950. It's in these gardens that the Petermännchen allegedly made his first documented appearances in 1593, according to ducal chronicles. The Schweriner See, a 64 km² glacial lake with maximum depth of 52.4 meters, has bathed the castle shores since the 13th century and served ducal navigation from 1350, now an ornithological nature reserve since 1970.
Your investigation of the Petermännchen has led you from Gothic vaults to Renaissance gardens, revealing how Schwerin concentrates seven centuries of Mecklenburg heritage within a 1.5 km perimeter. Between medieval cathedral and modern parliamentary castle, you take away an understanding of a city that preserved its ducal heritage while adapting to German political evolutions, watched over by the benevolent spirit still guarding its century-old stones.
