Anniversary 2026 Thursday, 23 July 2026

Join us as we kick off the anniversary weekend and discover the first exciting activities today!

Four days, over 40 events: look forward to a packed anniversary weekend! As well as the major highlights, you can put together your very own programme from a wide range of other activities. Today’s recommendation: Aus der Negev-Wüste nach Heidelberg – Ein Leben mit Geschichte(n)

Please note: Some events have a limited number of participating places. Registration for these events opens on 15 June 2026 for all members and guests registered for "30 Years HAI". Some events take place at the same time and therefore cannot be attended simultaneously. Please also refer to the relevant daily schedule to help you plan your day. Please make your selection by 30 June 2026 if possible. Thank you!
