The palazzo del Capitaniato was designed by Andrea Palladio in 1565 and built between 1571 and 1572. The palazzo is currently used by the town council. It was decorated by Lorenzo Rubini and, in the interior, with frescoes by Giovanni Antonio Fasolo. Since 1994 the palace has been part of the UNESCO World Heritage Site of the 'City of Vicenza and the Palladian Villas of the Veneto'.
The Palladian loggia replaced an analogous building which had stood on the same site from the Middle Ages, and which had already been reconstructed at least twice during the Cinquecento: a covered public loggia on the ground floor and an audience hall on the upper storey. The new construction became economically viable in April 1571 and works began immediately. Palladio supplied the last drawings for the moulding templates in March 1572 and by the end of that year the building would have been roofed, since Giannantonio Fasolo could paint the lacunars of the audience hall while Lorenzo Rubini could execute the stuccoes and statues.
While the upper hall displays a flat, coffered ceiling, the ground-floor loggia has a sophisticated vault covering, certainly to better sustain the weight of the hall. The overall design is extremely sophisticated, as witnessed for example by the portals which open within the niches and follow their curvature.
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.
