Resolven (Solfen) - From 'A Topographical Dictionary of Wales' (1849)
RESOLVEN (SOLFEN), a township, in the parish of Lantwit-juxta-Neath, union and hundred of Neath, county of Glamorgan, South Wales, 7 miles (N. E. by E.) from Neath; containing 500 inhabitants. This place is situated in the upper part of the parish, near the left bank of the river Neath, where the mountains are lofty and rugged, and their declivities and the glens well covered with timber. It comprises 5000 acres, of which 2000 are common or waste. Solven Hill is an elevated mountain in the hamlet, at the western base of which, overlooking the Neath, are the remains of Glyn Castle; the streams that flow into that river down the glens of the mountains form many pleasing cascades. Here is a chapel of ease to the parochial church. The tithes have been commuted for �70, of which �55 are payable to the impropriators, and �15 to the rector.
