Ruotsinsalmi fortress was built by Russians in 1790-1796. It was part of the South-Eastern Finland fortification system which was planned to defence St. Petersburg. The sea fortress was located to islands in front of the city of Kotka and Kyminlinna fortress. It contained three main strongholds (Fort Katarina, Fort Elisabeth and Fort Slava) and several redoubts and artillery batteries.
Ruotsinsalmi fortress lost its original defensive value only couple of years later, when rest areas of Finland were joined to Russia after the Finnish War (1808-1809). It was disbanded in the 1830's and during the Crimean war (1855) Anglo-French fleet destroyed the empty fortress permanently.
Today individual remnants of fortresses can still be found for instance beside Catherine’s path and on the island of Tiutinen. Also Fort Elisabeth's embankments have been renovated in recent years. The island is easily accessible by regular boat services in the summer.
Montparnasse Cemetery was created from three farms in 1824. Cemeteries had been banned from Paris since the closure, owing to health concerns, of the Cimetière des Innocents in 1786. Several new cemeteries outside the precincts of the capital replaced all the internal Parisian ones in the early 19th century: Montmartre Cemetery in the north, Père Lachaise Cemetery in the east, and Montparnasse Cemetery in the south. At the heart of the city, and today sitting in the shadow of the Eiffel Tower, is Passy Cemetery.
Montparnasse cemetery is the burial place of many of France's intellectual and artistic elite as well as publishers and others who promoted the works of authors and artists. There are also many graves of foreigners who have made France their home, as well as monuments to police and firefighters killed in the line of duty in the city of Paris.
The cemetery is divided by Rue Émile Richard. The small section is usually referred to as the small cemetery (petit cimetière) and the large section as the big cemetery (grand cimetière).
Although Baudelaire is buried in this cemetery (division 6), there is also a cenotaph to him (between division 26 and 27). Because of the many notable people buried there, it is a highly popular tourist attraction.
