First considerations for a Word Heritage candidature of the pile dwellings took place in Switzerland in 2003. After adding the project to the Swiss Tentative List in 2004, official contacts with other States Parties took place. From 2007 to 2010, the six participating States Parties prepared the nomination file according the Operational Guidelines.

This nomination file Prehistoric Pile Dwellings around the Alps has been submitted in January 2010. At the same time the participating States Parties implemented an intergovernmental management agreement. The first meeting of the International Coordination Group took place 4 May 2010 at Ljubljana.
The candidature will be reviewed before May 2011 by an organisation commissioned by UNESCO. In this case ICOMOS mandated an expert for the Evaluation Mission. This expert visited the pile-dwelling sites in September and October 2010 and has authored a report. 
By letter of 14 December 2010, ICOMOS asked for clarification of several issues (Additional Information), above all a clarification on the contribution of each single component to the overall Outstanding Universal Value. This Additional Information submitted in Paris together with a reduced list of 111 component parts and the revised Management Plan Version 2.0 end of February 2011.

In May, ICOMOS recommended to inscribe the nomination to the World Heritage List. The 24 June, World Heritage Committee inscribed the prehistoric Pile Dwellings around the Alps on the World Heritage List at the occasion of the 35th session in Paris from 19 to 29 June 2011.
