Much later, in the 17th century, as it lies on the old Great North Road, it became an important staging post and a number of coaching inns remain as public houses. After the Great Northern Railway by-passed the village due to the objections of local landowners, Welwyn became less important. Having previously been seen as a town on par with Hatfield and Stevenage, it gradually was seen as a village. The 20th century brought major expansion to the area, as estates to the south, west and north of the village were built up.
