Flag days

Why do we hoist the flag? See which days Sonderborg Municipality raises Dannebrog (the Danish flag).

Flags are flown at the town hall in Sønderborg. At the municipality's schools, institutions and nursing homes as well as other buildings where there is currently a flagpole, flagging is encouraged on flag days.

The flag will be hoisted on the following days in 2023:
