The Waldschlösschen Bridge (German: Waldschlößchenbrücke or Waldschlösschenbrücke ) is a road bridge across the Elbe river in Dresden.
 The bridge was intended to remedy inner-city traffic congestion.
 Its construction was highly controversial, as the Dresden Elbe Valley had been declared a UNESCO World Heritage Site and UNESCO expressed strong concerns against the bridge, noting its intent to withdraw the World Heritage title if the bridge were built.
 As a result of this project, the Dresden Elbe Valley was listed in 2006 as an "Endangered World Heritage Site" (one of two in Europe, the Medieval Monuments in Kosovo being the other one), and in 2009 became only the second World Heritage Site to be de-listed.

Saint Sophia Cathedral in Kiev is an outstanding architectural monument of Kievan Rus'.

Rapa Nui National Park is a national park and UNESCO-inscribed World Heritage Site located on Easter Island, Chile.
 Rapa Nui is the Polynesian name of Easter Island; its Spanish name is Isla de Pascua.
 The island is located in the southeastern Pacific Ocean, at the southeastern extremity of the Polynesian Triangle.
 The island was taken over by Chile in 1888.
 Its fame and World Heritage status arise from the 887 extant stone statues known by the name "moai", whose creation is attributed to the early Rapa Nui people who inhabited the island around 300 AD.
 Much of the island has been declared as Rapa Nui National Park which, on 22 March 1996, UNESCO designated a World Heritage Site under cultural criteria (i), (iii), & (v).
 The park is under the administrative control of the Corporación Nacional Forestal (CONAF), which provides legal protection to the total area of the island.
 As Easter Island has insufficient resources for conserving its natural heritage, the Government of Chile and the National Council of Monuments have provided financial support for the conservation efforts.
