Carmarthen Castle  was first built by Walter, Sheriff of Gloucester in the early 1100s. It was captured and destroyed on several occasions before being rebuilt in stone during the 1190s. The castle was captured by Owain Glyndŵr in 1405. Henry VII's father died at Carmarthen Castle in 1456. During the Wars of the Roses the castle fell to William Herbert and, during the Civil War, was captured by Parliamentary forces. It was dismantled by order of Oliver Cromwell in the mid 1600s.

It has been used as the site of Carmarthen's gaol until the 1920s. The remains of the castle were given a Grade I heritage listing in 1954 and is currently a tourist attraction and site of the town's Tourist Information Centre.

The castle is accessed today via the surviving 13-metre-high gatehouse on Nott Square or alternatively via the Old Castle Gaol entrance on Castle hill.

Now, most of what's left of this castle is accessible, but the most interesting information boards are up steps. Also, parking nearby is an issue.

We travelled here from Cardiff for something to do on a spare day, there is not much to see really only one end of the castle remains we walked around the whole place in 10 mins.. My advice go to Cardiff Castle much better to see

What’s left of this castle is great to walk around, worth stopping by to have a look if you’re in the area. There’s no entry fee, it’s free to visit. There are information boards dotted around to tell you about the history of the castle. It doesn’t take long to walk around the ruins but it’s worth visiting.

Travelled to Carmarthen Castle from Kent 5 hours drive and I can tell you I was not disappointed.... It was worth every penny of the free entry and a powerful reminder of days gone by. Fantastic information about those that lived in the time of the Castles erection and we were fortunate to visit during an off peak season as we had the run of the castle to ourselves. Simply glorious.

Seaplane Harbour Museum

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.
