In a short span of years, Tvøroyri grew into a large village, mainly after 1856 when the monopoly state of the store was abolished.
Around the turn of the 20th century, Tvøroyri was one of the largest towns on the Faroe Islands and had one of the main fishing industries.
Trongisvágur is home to the large Sports Centre, the children's institutions and the football stadium "Stórá".
Stórá is the home of TB – Tvøroyrar Bóltfelag, the oldest football team of the Faroe Islands.
Down by the harbour, north of Seglloftið, lies a square covered by flat stones.
