Along the road on the Dutch side is the 35 metres (115 ft) Wilhelminatoren observation tower, with a restaurant and forest trails. The present tower officially opened on 7 October 2011 and features a lift and a glass floor. The first tower at the site was built in 1905 during the reign of its namesake, Queen Wilhelmina of the Netherlands, and was demolished in 1945. The second 20 metres (66 ft) tower opened on 11 August 1951 and was demolished over the winter of 2010–2011 because of its poor condition and high maintenance requirements.[citation needed]
