Miercurea Nirajului, which in 2003 became a town, is located on the middle stream of the Niraj River, at the confluence with the Nirajul Mic rivulet, 21 km away from Târgu-Mures. The archaeological vestiges discovered in the area demonstrate that it has been inhabited ever since the Neolithic. Stone made hammers were found in Miercurea Nirajului, dating from 2000-1700 b.Ch. In Laureni, Byzantine coins were found, dating from emperor Justinianus' time, while the Roman road, leading to the Calugareni camp, crosses the border line of the Mosuni and the Beu villages.
The name of the town Szereda comes from the Slavic "sreda", which means "market place" also has the meaning of "centre". Documentary evidence dates from 1493. The events that took place between 1600-1603 devastated the area. General Basta left Transylvania in 1604. In 1605 the Diet of Transylvania was called in Miercurea Nirajului.
     On February 21st 1605, Bocskay István was elected Prince of Transylvania, and thus the name of the town entered the annals of history.
     For a long period of time Miercurea Nirajului had been the administrative center of Mures district, a place where the community leaders' assemblies were held. In the XVIIIth century the administrative center of the district moved to Târgu-Mures. Deprived of its former glory, Miercurea Nirajului eventually lost its importance and turned into a rural location. After the bourgeois revolution of 1848 the place went through a spectacular development and after 1919, the first factories and tradesmen's workshops appeared in the area. Between 1970 and 1980 the industry developed, the school system extended, blocks of flats were built, the House of Culture was opened. Since the 1989 revolution a significant development has been taking place, mainly in the private business.
     Starting from 1995, many economic units have been opened, like for instance: a wood processing factory, a furniture factory, a mill, a bakery, a meat processing factory etc. Besides the two kindergartens and the secondary school, there are also a college and a vocational school as well as the Center for Horticulture Consulting and the Horticulture School (long distance education system).
     In 1997 the local council approved the general town planning and in September 2002 a referendum was organized, and as a consequence the place regained its former status of a city. Documentary evidence of the included villages: 1332 - Beu , Laureni (Sancto Laurentio); 1360 - Sardu Nirajului (Saard); 1446 - Mosuni (Moson); 1484 - Dumitrestii; 1494 - Tâmpa (Thompa) ; 1567 - Veta (Wicke).
