Village in the parish of Malew, immediately beside Rushen Abbey and the Silverburn.

Ballasalla grew at an important crossing of the Silverburn on the road between Castletown and the centre of the Island. Its oldest surviving structure is the Crossag, or Monk's Bridge, which nineteenth-century antiquaries considered likely to date from the period of the neighbouring abbey.

The bridge was already regarded as ancient in Waldron's time. A note in the Manx Society edition of his description called the Ballasalla crossing the oldest of the Manx bridges and connected it directly with Rushen Abbey. Bridge maintenance was a public responsibility: an Act of Tynwald in 1739 levied one penny a year on inhabitants between sixteen and sixty to repair decayed bridges and provide new crossings elsewhere.

Rushen Abbey stood immediately outside the village on the western bank of the Silverburn. The abbey buildings, lands, mills and tenants shaped Ballasalla for centuries, while the river supplied both the religious house and the later village.

Ballasalla also served as a local market and fair centre. Waldron's notes identify it as a market for fowls, and Robertson's eighteenth-century list records fairs at Ballasalla in April, August and September.

The village stood on the route between Castletown and Douglas, close to the crossing towards Derbyhaven and Ronaldsway. Its position beside the abbey, river and bridge made it one of the principal stopping points in the southern interior.
