Church towers lining the coast were once used as beacons for the benefit of sailors and as reference points in the landscape to assist travellers. Eight towers in the Province of Groningen have been designated as official 'Landmerk' (Landmarks), and three of these are to be found in Waddenland. Striking art pieces can be enjoyed in the participating churches. The church of Hornhuizen for example presents an enormous chandelier created by designer duo Studio Job.
Climb up one of these public lookouts and scan the sea. The key can be found at one of the key safekeeping addresses in the village.
