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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
