At present, the Netherlands has a Tentative List of Archaeological Monuments and a Tentative List of Structural Monuments.

Tentative List of Archaeological Monuments (1994):
Wierden area of Middag-Humsterland (Groningen) (Terpenlandschap [Dwelling mound landscape])
Roman fort at Bunnik-Vechten (Utrecht)
Prehistoric sites in the Gouw polder and the Groet polder (Noord-Holland)
Prehistoric sites at Swifterband (Flevoland)
Prehistoric sites in marshes east of the Alblasserwaard (Zuid-Holland)
Remnants of the Roman city of Forum Hadriani in Voorburg (Zuid-Holland)
Remains of ships in the western part of the Wadden Sea (Noord-Holland, Friesland)

Tentative List of Structural Monuments (1995):
Historical centre of Amsterdam (Noord-Holland)
New Dutch Inundation Line (Noord-Holland, Utrecht, Zuid-Holland, Gelderland, Noord-Brabant)
Van Nelle factory in Rotterdam (Zuid-Holland) (Former factory building)

There is as yet no Tentative List of natural heritage in the Netherlands. There is, however, an agreement between the governments of Denmark, Germany and the Netherlands to work together towards having the Wadden Sea inscribed on the World Heritage List. (This is a mixed site due to the presence of shipwrecks).
