Grobiņa (pronunciationⓘ; German: Grobin) is a town in South Kurzeme Municipality in the Courland region of Latvia, eleven kilometers east of Liepāja.

The weathered surface of one side contains refined carvings – inside the ring of ornaments there are two waterbirds; their beaks meet.

[6] The Norsemen may have remained in control of Grobin until the mid-9th century, when – as Rimbert's Vita Ansgari relates – people inhabiting the Courland regions of Latvia rebelled after a long period as tributaries of Swedish rulers.

Then Olof (I) of Sweden gathered an enormous army and tried to win back the former colony, in the process destroying a place that Rimbert calls Seeburg, usually identified as Grobin.

When they were preparing for a decisive battle, the Curonians suddenly sued for peace, giving as booty weapons and gold captured by them from the Danes a year earlier.

He found evidence of a large-scale conflict in the 9th century, notably large concentrations of Swedish arrowheads near the walls of the derelict Curonian fortress.
