Segontium Romon Fort is an impressive excavated fortification located just outside Caernarfon. It was founded by Agricola in AD77, and it was garrisoned for over three hundred years. It was the longest-held Roman fort in Wales and used to hold a 'cohors milliaria,' a regiment of about 1,000 auxiliary infantry, mainly recruited from Belgium and Germany. It was linked by Roman roads to the main legionary bases at Chester and Caerleon by a series of marching camps and other forts.

Dolbadarn Castle controlled an important route into the heartland of medieval Gwynedd and was close to rich cattle pastures that provided food and income. Begun in the 1220s, the castle was built in ten years. The round tower consisted of two floors with comfortable accommodation over a basement and was a princely castle... The builder Llywelyn ab Lorwerth died in 1240, and despite his efforts to secure a peaceful succession in Gwynedd, a struggle began that did not find a clear winner until 1255. Llywelyn's grandson, Llywelyn ap Gruffudd, defeated his brothers in battle and became Prince of Gwynedd. But they still posed a threat, and Llywelyn held Owain Goch, his eldest brother, prisoner in Dolbadarn. Here he was held captive for twenty-two long years. The 13th-century poet Hywel Foel ap Griffri described Owain as "a man in the tower, long a guest."

A beautiful, large Castle with many towers you can gogo up to have a great view of the surrounding area. A very rewarding destination for any tour. if you go in, plan at least 1-2 hours to go everywhere, or just admire the walls from outside.

The best time to visit the castles around Llanwnda is generally during the spring and summer months (April to September) when the weather is milder and days are longer, allowing for more comfortable exploration and better visibility of the scenic surroundings. However, visiting in the shoulder seasons (early spring or late autumn) can offer fewer crowds and beautiful seasonal colours, though some facilities might have reduced hours. Winter visits can be dramatic, but be prepared for colder weather and potentially limited access.
The region offers a mix of both. While many of the grander castles like Caernarfon, Conwy, Harlech, and Beaumaris were built by Edward I during the English conquest, you can also visit significant native Welsh strongholds.

The time needed varies by castle. For a comprehensive visit to a major site like Caernarfon Castle, it's recommended to allow 2 to 3 hours to fully explore its vast structures, museum, and grounds. Smaller sites like Dolbadarn Castle or Segontium Roman Fort might take less than an hour. If you plan to visit multiple castles in a day, factor in travel time between locations.
