"Mariehamn - Castles and Countryside " a Mariehamn Travel Page by MikeAtSea

Mariehamn was named after Marie Alexandrovna, the Empress consort of Alexander II of Russia. Founded in 1861, the city is located on a peninsula and is known as the “town of a thousand linden trees”.
Åland and Mariehamn have a reputable heritage in shipping. The Flying P-Liner Pommern museum ship is anchored in the Western Harbour. The Eastern Harbour features one of the largest marinas in Scandinavia. The famous Dutch steamer Jan Nieveen (now called F.P. von Knorring, after Åland teacher and vicar Frans Peter von Knorring) can also be found here.
The main pedestrian street, Torggatan, is a colourful and crowded hive of activity, and together with good museums, offers the visitor a leisurely day’s exploration.
