This connection groups WHS that are also European Heritage Label sites.

"European Heritage sites are milestones in the creation of today's Europe. Spanning from the dawn of civilisation to the Europe we see today, these sites celebrate and symbolise European ideals, values, history and integration. Since 2013, these sites have been selected for their symbolic value, the role they have played in European history and the activities they offer. These sites bring the European Union and its citizens closer together."
