The Ehrensvärd Museum is located by the original central courtyard of the fortress, in the old Commander’s House. The interior of the museum illustrates an 18th century residence. The collection includes paintings, furniture, weapons, and ship models portraying vessels of the Swedish Archipelago Fleet. The first resident of the building was Augustin Ehrensvärd (1710-1772), the founder of the Suomenlinna fortress. The Commander’s House is a good example of how housing and the defensive system were connected under the same roof. The building’s side wings also functioned as fortification bastions and it was possible to access the bastion terrepleins directly from the rooms. In case of an emergency the windows of the dining room as well as of the sleeping alcove could be used as crenels from which the main entrance to the fortress, the Artillery Bay, could be defended. The building was used as the commander’s residence until 1855, when it lost its southern wing in the Crimean War. In 1927 the Ehrensvärd Society made an initiative to establish a museum in those rooms that had served as Ehrensvärd ‘s residence. The museum was opened in 1930. Museum is open in summertime.

Designed by the founder of Suomenlinna, Augustin Ehrensvärd, the Great Courtyard was completed in the 1760s and served as the main square and administrative center of the entire fortress. The courtyard was bordered by buildings such as the Commandant’s House, which served as the residence of the fortress commandants, and the main guardhouse. The Blue Route passes through the Great Courtyard. From May to the end of September, the water bus operates to the Tykistölahden pier, which is about 200 meters from the Great Courtyard. The status of the administrative center was emphasized architecturally as well. The placement of the buildings and the curved facades of the square created a false perspective, enhancing the grandeur and ceremonial appearance of the square. In the center of the square is the tomb of Augustin Ehrensvärd, with an impressive monument designed by King Gustav III of Sweden and completed by Ehrensvärd’s son Carl August together with Johan Tobias Sergel. Ehrensvärd died in 1772, but he was temporarily buried elsewhere for 10 years while waiting for the completion of the Viapori tomb. The tomb monument was finally completed just before the end of Swedish rule in the early 19th century.

Site of an old castle, nowadays all that's left to see is a series of circular earthworks. Cycling is forbidden on the earthworks themselves.

Perched high above the hustle and bustle of central Porvoo in peaceful Iso Linnamäki Park, it's hard to imagine that it was the scene of fierce battles during the Great Northern War in the 18th century. Half a millennium ago there was a castle dominating the entire Porvoo River Valley. It was probably built by the Swedes during their conquest of the East. The steep moats around the top of Linnamäki Hill are a reminder of the past.

Former castle complex situated on a hill, which was probably laid out by the Swedes at the beginning of the 13th century
