Westergoa

Westergoa was one of the Seven Sealands and one of the three that now lie within the borders of today's Dutch province of Friesland. Later it was one of the three goaen of Frisia. In the Middle Ages Westergoa most probably formed the political centre of the Frisian realm.

== Area == On the eastern side Westergoa was bordered by the Middelsee, on the other side Eastergoa. On the south side it bordered with what originally was Bornegoa which was in the line with Terhernster Lake to the south of the coast, the eastern perimeter was with Doedingwerstal.
