Herbrechtingen is a town in the Baden-Württemberg province of Germany, and is a twin town of Biatorbágy from 1989. Herbrechtingen was first mentioned in a charter of Charles the Great. This charter was issued probably in Düren, on 7th September 774, and it is now in the National Archives in Paris. However, the village is undoubtedly older than its first mention - as evidenced by its location, archaeological finds and place names. The ground plan of the village is determined by the flow direction of the River Brenz. It flows from the south, from the direction of Eselsburg Valley, and turns east shortly after the mouth of a stream. Thus it forms a triangle with Lange Straße (Long street) and Mühlstraße (Mill street), so the centre of the village is protected from the west and the north.

The village situated in Székely Land is a twin town of Biatorbágy from 2001. The Gyergyó Basin, in which Gyergyóremete is situated, is the northernmost, highest and has the coldest winters (average temperature in January: –6 °C, but temperatures as low as –35 °C are not rare) among the larger basins in Székely Land. The meteorological station in Gyergyóalfalu measured a national cold record in Romania on several occasions. It is the source Basin of the River Maros, surrounded by the volcanic ranges of the Hargita – the Görgényi Alps – the Kelemen Alps.
