This microregion still remains a white spot on the ethnographical maps of our days, from several perspectives. This is one of the reasons why it is impossible, or at least very difficult to discuss the theme of folk architecture of the Plain Valley of the Mureș River. Another, more important obstacle is the fact that due to the modernization and industrialization processes, started from the second half of the 20^th century, step by step these buildings were demolished. New houses and other buildings were built according to the socialist doctrines, thus the villages of the microregion became standardized, with a general aspect dominated by standard houses and stores, with schools and community centers built in the well-known style of socialism

In case of the villages situated in the narrow valleys of the hilly land between the Mureș and the Niraj rivers, traditional peasant houses survived in a larger number, the oldest and the most beautiful being those from Mura Mică, Ilioara, Pădureni, Petrilaca and Iara de Mureș. Also it can be observed in the case of the villages on the right bank of the Mureș River, in the area of the Transylvanian Plains. Here there are also very few settlements, that are difficult to access (Merișor, Păingeni, Moișa și Toldal) where a larger number of traditional houses and properties were preserved. Unfortunately most of these buildings are abandoned.

Besides these, there is another architectural element that takes us towards the concept of traditional architecture, these are the gates called fedeles kapu (roofed gate), realized of wood, but also stone, in a much reduced number. Another element of rural architecture is represented by the public buildings from late 19^th century and early 20^th century, such as confessional school in Iara de Mureș and Petrilaca, the rectory from Glodeni and Dumbrăvioara, the Wigand school in Dumbrăvioara and so on.
