ARCHES Expert meetings are typically condensed (1-2 days), focused (on a 'hot' niche topic in heritage) and limited in participants (round table style with invited experts).

In this way, Expert Meetings offer a highly efficient seminar format that is welcomed by the heritage field. The format aims to offer a complementing alternative to the well-established, but relatively long multi-day conferences, and this by means of efficient workshops singling out one particular sub-topic that can be approached in a interdisciplinary manner.

After consultation with peers, an ARCHES member invites a number of researchers that are dealing with a specific heritage-related issue, allowing for an effective exchange of research outcomes and ideas while defining potential future avenues to pursue. This event is typically condensed in one or two days and is often organized in a relevant institute or location permitting an on-topic field trip.
