received a donation of 24,000 NOK for a carillon in the belfry, but this was never implemented. In 2003 a second donation, by Ørnulf Myklestad, resulted in a 48-bell concert carillon under the direction of carillonneur Vegar Sandholt. This carillon is inside the tower not the belfry, and the acoustical problems arising this location have been highlighted in a 2005 masters thesis by Laura Rueslåtten for the Scandinavian Carillon School. From December 2016 the carillon has been in regular use for hour, quarter-strokes and ritornelles, with contributions by Vegar Sandholt and Kåre Nordstoga, programmed and maintained by Brynjar Landmark, and with 18 different melodies between 7:00 am and midnight, changing according to the calendar.
