Kilmainham Gaol is one of the largest unoccupied gaols in Europe. It opened in 1796 as the new county gaol for Dublin and finally shut its doors as such in 1924. Today, the building symbolises the tradition of militant and constitutional nationalism, from the rebellion of 1798 to the Irish Civil War of 1922-23. The great collection consists of a wide variety of object types, including manuscripts, photographs, newspapers, weaponry, artwork, medals, uniforms and personal effects especially related to the political imprisonment in the 1916-23 period, as well as the experience of women during the Civil War.

Under the shelter of lush rainforest, the archeological site of Kohunlich is an outstanding example of Maya architecture. Palaces, citadels, temples, such as the top attraction Temple of the Masks, and other elaborate structures are scattered over an area of more than 20 acres, with most landmarks dating back to as early as 250 to 600 AD. Chetumal is a common starting point to visit Kohunlich, but tours are available at the Costa Maya Cruise Port as well. If you are in the area, don't miss out on the opportunity to visit Dzibanche, another outstanding Maya landmark around 20 miles away from Kohunlich.
