The Early Christian Centre occupied one of the Roman Emona's building plots, which usually measured from 3,000 to 3,600 square metres and were demarcated by four roads. The Centre was located in the vicinity of the Forum and the western town wall, the remains of which have been preserved in the Erjavčeva cesta road across the way from the Cankarjev dom cultural and congress centre. Like most of the buildings in Emona, the Early Christian Centre, referred to by archaeologists as Insula No. 32, was originally a private dwelling, later converted into a public complex. The remains of its foundations and original paving date from the 1st century AD, the time when Emona was first built. The earliest extensive renovation took place at the beginning of the 4th century AD. Renovated paving and newly built pools indicate that the building was turned into public baths.
In the second half of the 4th century, a colour mosaic depicting early Christian symbols was laid along the building's northern façade. Written sources suggest that at the beginning of the 5th century the building was renovated and converted into a centrally heated parish complex. A rectangular baptistery with a small pool was built next to the main courtyard, and to the south of it a large portico (covered walk) with a colour mosaic sufficiently preserved to reveal the name of its maker, Archdeacon Antiochus. The parish complex was pulled down at a time unknown.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.
