Since 2005, ESPON has financed a number of transnational seminar events involving at least three countries. Several of these events have already taken place, and one of these - the MontESPON Seminar - was held in Switzerland on 5 and 6 September 2006 in Lucerne. The seminar, which was attended by the representatives of seven countries, looked at issues relating to Europe's mountainous regions. Its aim, in particular, was to achieve a better understanding of the specific challenges in these areas, taking into consideration findings of the ESPON and Interreg III B projects. The forum participants attended a total of 16 workshops on various problems specific to these regions, with a concluding report published in November 2006. This final report and the presentation documents are available online.
