Rollag is a municipality in Buskerud county, Norway. It is part of the traditional region of Numedal. The municipality of Rollag was established on 1 January 1838 (see formannskapsdistrikt). Nore og Uvdal was separated from Rollag in 1858.
The administrative centre of the municipality is the village of Rollag, although the most populated area in the municipality is Veggli. Rollag is bordered in the north by Nore og Uvdal, in the east by Sigdal, in the south by Flesberg, and in the west by Tinn (Telemark county).
The municipality (originally the parish) is named after the old Rollag farm (Old Norse: Roll(u)lag), since the first church was built here. The first element is probably (the genitive case of) a river name Rolla (now called the Troelva river) and the last element is lag which means "fishing place". The meaning of the river name is unknown (maybe "the shivering").
The coat-of-arms is from modern times. They were granted in 1993. The arms show two gold-colored lines on a red background. The lines represent an old warning cairn made of timber.
Attack!!!!
We are one and many a driving force consuming the enemy
Vengeance is mine for the time when their foot shall slip
The day of tragedy is at hand
So their doom comes swiftly
Uncontained hatred rains like fire from the sky
The wind and the storms and the fire is on our side
They sow the wind and shall reap the whirlwind
Men will be annihilated and women will be raped
Temples are ablaze we set fire to your faith
Where are your gods the rock in which you took refuge
Who drank the blood the wine of your libations?
Now nothing more than a memory in a mouth of Ashes
The day of tragedy is at hand
So their doom comes swiftly
See now that I, even I am he I am the god to be
I hold my hand to the sky and command from the throne
As I live forever when I whet my flashing sword
And my hand takes hold on Judgement
I will have Vengeance
