Gnomonica Baltica

There was planned a new conference Gnomonica Baltica in 2021, Riga (57°N, 24°E). Due to possible serious uncertainties over possible travel and public event restrictions in 2021 (caused by COVID-19), it has been decided to move to conference to 2022.

The conference will focus on historical and modern gnomonics in the Baltic region, as well as share sundialling experience and impressions from all around the world.
