The castrum doloris (Latin for castle of grief) was a structure and set of decorations which sheltered and accompanied the catafalque or bier in a funeral.
It signified the prestige and power of the deceased, and was common in Poland-Lithuania and other parts of Europe.
Sometimes it would be supplemented by candles, coats of arms, epitaphs and allegorical pictures, in which case it was also called a chapelle ardente.
Sigismund II Augustus was one of the first Polish rulers to have a castrum doloris in the 1570s.
