Vestmanna is the largest village on Streymoy.

It lies on the west coast and has a view towards the island of Vágar.
Vestmanna was the port of call of the ferry from Vágar and the airport. Thus all the traffic to and from the airport passed Vestmanna. That is over now. A submerged tunnel now connects the two islands and has replaced the old ferry. The traffic enters the tunnel from just above the village of Leynar and therefore the traffic is not passing Vestmanna any more.

People in Vestmanna mainly live by the fishing-industry. There is a fillet-factory in the village that takes fish from the modern fishing-fleet.
In the inlet of Vestmanna there is fish farming.
Also Vestmanna has production of standard houses and a slipway.

Since 1953 Vestmanna has provided electric power to the islands by its hydroelectric power stations. In a
valley high above the village there are dams providing water trough large tubes to the three power stations in the village.

Vestmanna is popular with tourists due to the fact that it is a charming village but especially because boat
trips are arranged from Vestmanna to Vestmannabjørgini. These are impressive bird cliffs and caves just outside Vestmanna. When the weather allows it several trips are arranged a day. They start from the ferry
port and one trip takes about 3 hours.

In the beginning of the 17th century Vestmanna was pestered by pirates. In 1615 Danish warships in  Vestmanna surprised three Irish pirate-ships. 27 Irish pirates were killed in the fight. 55 were drowned after
the fight and 8 pirate-officers were executed by hanging.

In the middle of the 19th century a steal-net was stretched across the mouth of the inlet during whaling.  This was done after the pilot whales had been driven into the inlet to prevent them from escaping.
