Rough Castle Fort is a Roman fort on the Antonine Wall. The wall was built around 143 AD and stretched from Bo'ness on the River Forth to Old Kilpatrick on the River Clyde. The fort is the best preserved of the 19 forts constructed along the length of the Wall. Built against the southern rear face of the Wall, the fort was defended by 6 metre thick turf ramparts and surrounded by defensive ditches. Gateways were provided through the main Wall to the north, and also through the walls on the other three sides of the fort. Causeways were then constructed across the main Antonine and secondary defensive ditches, affording easy access to and from the fort.
The fort was the second smallest on the Wall and had an area of about 4,000 square metres. The fort contained several substantial stone buildings, including a headquarters, the commander's house, barracks, a bath house and a granary. Although the original buildings have not survived, the foundations of these buildings were discovered during excavations in 1902 - 1903, 1932 and 1957 - 1961.
Inscriptions found on recovered artifacts indicate that the fort was the base for 480 men of the Cohors VI Nerviorum of Nervii, an infantry unit recruited from a north-eastern Gallic tribe. The military road on the south side of the Wall, which enabled transport between all forts, is still well defined and there is also a fine length of rampart and ditch still intact to the west.
A feature of the defences at the fort, discovered during the excavations, is a series of pits lying to the north west of the causeway across the Antonine ditch. These pits, known as 'lilias', would originally have contained sharpened stakes at the bottom. The lilias were positioned to help defend the vulnerable northern gateway through the Wall. Near the fort were a turf platform (beacon platform or signalling platform) and gravel pits for building of the military road. Interesting was that the bath house was built on an annexe. The fort was defended by Nervii and Flavius Betto was a commanding officer.References:
The Seaplane Harbour is the newest and one of the most exciting museums in Tallinn. It tells stories about the Estonian maritime and military history. The museum’s display, that comprises of more than a couple of hundred large exhibits, revitalizes the colourful history of Estonia.
British built submarine Lembit weighing 600 tones is the centrepiece of the new museum. Built in 1936 for the Estonian navy, Lembit served in the World War II under the Soviet flag. It remained in service for 75 years being the oldest submarine in the World still in use until it was hauled ashore in 2011. Despite its long history, Lembit is still in an excellent condition offering a glimpse of the 1930s art of technology.
Another exciting attraction is a full-scale replica of Short Type 184, a British pre-World War II seaplane, which was also used by the Estonian armed forces. Short Type 184 has earned its place in military history by being the first aircraft ever to attack an enemy’s ship with an air-launched torpedo. Since none of the original seaplanes have survived, the replica in Seaplane Harbour is the only full-size representation of the aircraft in the whole World.
Simulators mimicking a flight above Tallinn, around-the-world journey in the yellow submarine, navigating on the Tallinn bay make this museum heaven for kids or adventurous adults.
Seaplane Harbour operates in architecturally unique hangars built almost a century ago, in 1916 and 1917, as a part of Peter the Great sea fortress. These hangars are the World’s first reinforced concrete shell structures of such a great size. Charles Lindbergh, the man who performed the first solo flight across the Atlantic Ocean, landed here in 1930s.
On the outdoor area visitors can tour a collection of historic ships, including the Suur Tõll, Europe's largest steam-powered icebreaker.
