Watch Friesland: Berltsum Church, come and have a look inside. video on DTube
This is an old Church, and this is also an old video in fact. Inside it was one the loveliest Churches in the area and I had a nice chat with a gentleman who attends regularly.
Unfortunately the Organ (built in 1780) wasn't in action on this visit, as that would have been nice to have caught it playing on film.
