Skagen Old church, also called as 'Sand-Covered Church' was built in the 14th century and dedicated to Saint Lawrence of Rome. It was a brick church of considerable size and located 2 km south-west of the town centre. The white church tower is all that is visible of the former church, the rest of it demolished and the neighboring village having been buried under the sand from nearby dunes.
The church was named for the patron saint of sailors, but was buried by sand from Råbjerg Milen. The desertification that hit the area in the 18th century led to the abandonment of the old parish church to the migrating sands. This area of dunes threatened the church and the village for centuries, and the planting of trees could not prevent further encroachment: the church itself was demolished in 1775. All the furniture, fittings, and interior decoration were sold or moved to a new church (Skagen Church 1841), while the church tower being left to rise above the sand.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
