In the neighborhood of the fort of Rainau-Buch, the remains of several other Roman buildings are visible. For instance, there is the ruin of a monumental gate in the limes wall near the modern village of Rainau-Dalkingen, about a kilometer north of the fort. Originally, it was a wooden construction, but it was rebuilt several times.
In the final phase, at the beginning of the third century, it must have had a façade like the stage of a theater, with rather plumb columns. In the upper part of the gate, there must have been a bronze statue of an emperor, perhaps Caracalla, who defeated the Germanic tribe of the Alamans in 213, and may have started his campaign from Dalkingen. Twenty years later, the Alamans stroke back, and the gate was burned down.
References:The Broch of Clickimin is a large and well preserved, though somewhat restored broch near Lerwick. Originally built on an island in Clickimin Loch (now increased in size by silting and drainage), it was approached by a stone causeway. The water-level in the loch was reduced in 1874, leaving the broch high and dry. The broch is situated within a walled enclosure and, unusually for brochs, features a large 'blockhouse' between the opening in the enclosure and the broch itself. Another unusual feature is a stone slab featuring sculptured footprints, located in the causeway which approached the site. Situated across the loch is the Clickimin Leisure Centre.
