Sundalag
The Sundalag or Sundalagið describes the area on both banks of the Sundini , a strait of the Faroe Islands between the main islands of Streymoy and Eysturoy .
Places on the Sundalag are on the Streymoyer side from south to north: Kollafjørður , Hósvík , við Áir , Hvalvík , Streymnes , Langasandur , Haldarsvík and Tjørnuvík .
On the Eysturoy side from south to north: Morskranes , Selatrað , Oyri , Oyrarbakki , Norðskáli , Svínáir , Ljósá and Eiði .
The largest commune in the region is the Sunda kommuna , which today includes areas on both islands. The Tórshavnar kommuna extends further south on the Streymoyer side, as does the Sjóvar kommuna on the Eysturoyer side. The municipality of Eiði in the north of Eysturoy finally lies entirely in the Sundalag.
Common to the residents on both sides of the sound is their dialect of the Faroese language , which is part of the Eysturoy / North Islands dialect.
