Cefn Mawr also received funding in 2005
Two towns are to receive £2.5m funding for regeneration from the Heritage Lottery Fund (HLF).
Pontmorlais, in Merthyr Tydfil will receive more than £1.6m, and Cefn Mawr, Wrexham, will get over £870,000.
The money is part of HLF's Townscape Heritage Initiative which aims to help fund areas which have suffered "serious social and economic decline".
The money will be spent on repairing and preserving key buildings in both areas.
Jennifer Stewart, head of HLF in Wales, said: "This money will help support local authorities and residents to transform their towns, making essential improvements and repairs that will encourage local businesses and visitors back into these once vibrant areas."
In Pontmorlais, the money will be spent on buildings in the High Street, many of which were built between 1770 and 1820.
Cefn Mawr was awarded £1m by the scheme in 2005 and the new money will focus on buildings in Crane Street and Well Street.
It is hoped the funding "will help encourage further business start-ups, maintain the new level of community pride and optimism and attract a wider tourism audience".
