It is the location of Foel Grochan, a slate quarry which together with Hen Chwarel and Ceunant Ddu formed the Aberllefenni Slate Quarry, which extracted rock from mediaeval times until the beginning of the 21st Century.
Plas Aberllefenni (also known as "Y Plas") was a mediaeval manor house, but the older section was demolished in the 1960s and only a later wing is still standing.
The village is the site of a field study site for secondary school pupils.
Aberllefenni was the terminus of steam and passenger services on the narrow gauge Corris Railway, which carried slate from the quarries for transshipment at Machynlleth. Aberllefenni Station (now demolished) was used as the basis for Glennock Station on the fictional Skarloey Railway and can be seen illustrated in the book Four Little Engines. Two horse-worked tramways extended the railway beyond Aberllefenni Station -
- Aberllefenni Quarry tramway connecting the slate mill in the village with the three quarries
- the Ratgoed Tramway serving Cymerau Quarry and Ratgoed Quarry
