Notable examples include Caernarfon Castle, known for its impressive walls and towers, and Conwy Castle, which features eight massive towers. These castles served various purposes, from military defense to royal residences. Today, they are popular tourist attractions, offering visitors a glimpse into Wales' past. Many castles, like Cardiff Castle, have been restored and host events, making them vital parts of Welsh culture and heritage.
