Kunstfest Weimar
21 August – 6 September 2026
Late August into early September
Central Germany's largest festival of contemporary arts, closing the city's summer at the turn from August into September.
Thuringian dentists' congress
The state's dental profession takes the congress hall for two days in September.
In 23 days
25–26 September 2026
A two-day professional congress at the Weimarhalle, run by Thuringia's dental chamber for everyone who works in the field rather than for consultants alone.
Only for one reason, and it is a practical one: the Weimarhalle fills, and so does the town. September is the month Weimar's congress business is busiest — this, the building-materials conference and the phlebologists all fall inside the same three weeks — and a visitor booking a room in that window is competing with several hundred delegates.
The programme is built for dentists, dental assistants, dental technicians, students and trainees together rather than for practice owners alone, under a motto about working from the root to the crown, with aesthetic dentistry as the theme. That breadth is unusual: a professional congress that treats the whole surgery as its audience.
