Llanelwedd is on the
right bank of the
Wye concentrated immediately north of
Builth Wells. Here meet the A470 (from Rhayader), the A483 (from Llandrindod Wells and Welshpool), and the
A481 (from Worcester). Being more populous, Builth dominates in the general perception of the area, and Llanelwedd's main network of streets can be perceived as part of the town rather than its own village.
A station named after its neighbour, Builth Wells, was opened in the village on the former
Mid-Wales Railway from
Newtown to
Brecon which ran through the village. This has since closed and nothing remains. The former site is used to access the fairground. The nearest mainline station is now
Builth Road which is around two miles away. The local stone is suitable for various uses, and the Llanelwedd Quarries dominate the landscape on the north-east side of the village. The community includes the hamlets of Llanfaredd and Builth Road. ==Governance==
