St. George kills the dragon on the hour and the dragon lets out a frightful wail. Kirsten Kimers chimes the quarters on her small bell and Per Dover strikes the hours on the large clock while Kirsten shakes her head nervously. The face of the clock shows all 24 hours of the day. The wail of the dragon is made by a bellows that pumps air into three out of tune organ pipes. The clock was built in the late 15th century.
