Þríund is on the third floor on the eastern side of Harpa next to Eldborg with a spectacular view of the fjord and the surrounding mountains.

The space is triangular and therefore pleasantly different from what usually happens with spaces like this. Þríund is suitable for smaller occasions, e.g. conferences, meetings, workshops, receptions and parties.

The name of the space is very suitable for a space in a concert hall as þriund is a so-called musical interval. An interval is the space between two notes in music or the combination of two notes.
