This monument commemorates the lives of the 1,198 people who perished on board the Cunard Liner Lusitania on the 7th of May 1915. Sunk by a German submarine during the First World War, this memorial pays homage to the often-forgotten Irishmen who enlisted in World War One.

Away from the water’s edge, Rarotonga offers some fantastic walking tracks and attractions. Notable sites include Highland Paradise, where visitors can explore traditional Cook Islands culture and enjoy breathtaking views and Black Rock, or 'Arai Te Tonga', which is a significant spiritual site for the islanders.

The Royal Palace of the Hague, also serving as the monarch’s workplace, may not be as exuberant as its counterpart in Amsterdam, but it is an impressive city centrepiece nonetheless. Built as a farmhouse in 1533, it was reformed and repurposed several times over the years, accommodating such pivotal historical figures as Voltaire and notable monarchs such as King Willem I until its most recent extensions in 1984, which have turned it into a working palace, where political and state affairs take place daily. The palace gardens are open to the public throughout the day and make a nice spot for a picnic, where anyone can enjoy the ponds, flowerbeds and marble statues with views of the royal stables, archives and the Dome of Fagel. Look out for the hidden corridors leading to the Old Hague District in one of the corners of the gardens.

One of, if not the most important centres for justice and peace in the world, Peace Palace comprises the United Nations International Court of Justice, the Permanent Court of Arbitration, the Hague Academy of International Law and the Peace Palace Library. Although this is a working palace, which means most areas are closed to the public, there is, however, a visitors centre where those interested can learn more about the history of the palace and the role it plays today in international justice via a free audio tour. On rare occasions, the palace opens its doors to the public for guided tours, but it is advisable to check well in advance if any dates are available as they are few and far between. In any case, the impressive surrounding gardens and Neo-Renaissance buildings are definitely a must-see.
