Posta Sandstone (German: Postaer Sandstein), also called Wehlen Sandstone (Wehlener Sandstein), only occurs on the eastern banks of the River Elbe at Alte Poste, near Herrenleithe, Wehlen, Zeichen and Posta. The thickness of the deposit is between 30 and 50 metres. It is also known as Überquader ("Over Ashlar") and has the smallest deposit of all the Elbe sandstones. ^[1] In 2008 it was being quarried in the areas around the village of Lohmen and in Wehlen.

In 2008, Posta Sandstone was being won in two quarries in the Wesenitz valley and it was being used for solid window and door frames, façade slabs, sculptor's blocks and high-profile masonry work. It is used especially in restoration work and sometimes also in new structures. The following is a selection of the structures built in Posta Sandstone:
