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.

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

Franeker,
Wildinge and
Wymbrits, called the

Het Bildt, was added to Westergoa but by the establishment of Sânwâlden,
Gaasterland,
Doniawerstal and
Lemsterland these parts in the south of Westergoa were lost. Also eight cities grew exceptionally in the Westergoa area; Harlingen and
Franeker in the Fiefdielen part,
Bolsward at the eastern side of Wildinge, now Wûnseradiel and at the southern point
Workum and
Hindeloopen. The rest of Wymbrits fell into three cities and six parts.
Stavoren,
Sneek and

grietenijen of
Wymbritseradeel and Hemelumer Oldeferd (and Noardwâlde).
