About Kulla
Kulla is a quarry south of Lönsboda in north-east Skåne province. Grey granite was quarried here on-and-off from the 1950s, and production has been continuous since the 1980s. Swedish Grey Kulla is an aesthetic, versatile stone with a warm grey colour, making it ideal for monuments and as a construction stone.
