In 1779, a new bridge was erected, on the present site, and during the 1820's a new road was constructed linking north and south Wales. These improvements led to the quickening growth of the town. However, the basic fabric of modern Builth dates largely from Victorian and Edwardian times. This growth, without doubt, resulted from the discovery of the health springs. The first recorded mention of the mineral waters at Builth was as far back as 1740. It was not until the 1830's that the Park Wells with its Saline, and the Glanne Wells with its Sulphur were well known. During the second half of the nineteeth century large numbers of visitors came to Builth to 'take the Waters' and a myriad of hotels, guesthouses and shops were built to accommodate them. This process was helped during the 1860's by the arrival of the railways, allowing visitors to travel to Builth with ease, from all over Wales and England. It is from this time that the word 'Wells' was added to Builth.
