A marble frieze from the Acropolis in Athens that was taken to Sweden by a naval officer 110 years ago and remained in his family's possession until last year is to be officially returned to Greece this week, a Stockholm museum announced Monday.

The marble fragment comes from the Erechtheion temple, built around 420 BCE and known for its ornamental decoration and pillars in the form of statues of women known as Karyatides, the Museum of Mediterranean and Near Eastern Antiquities said.

Birgit Wiger-Angner, a retired gym teacher, turned the piece over to the museum after reading an article about Greece's desire to recover friezes from the main temple of the Parthenon, which were taken by Britain's Lord Elgin in the nineteenth century and that London refuses to return.

Wiger-Angner inherited the piece - measuring 20 centimeters (7.8 inches) wide and eight centimeters high - from her father, whose brother Henning Lund acquired it from the Acropolis around 1895-96 and took it to Sweden.

Until February 2005, the frieze served as a decoration in Wiger-Angner's home.

Wiger-Angner is due to hand over the piece to Greek culture minister Georgios Voulgarakis at a ceremony to be held at the Acropolis Friday, the museum said.

Suzanne Unge-Soerling, assistant head of the museum in Stockholm, said that it was of great historical interest.

"Today the Erechtheion temple is a long way from being complete ... the frieze is a piece of a puzzle ... and the small number of similar pieces that have emerged ... are mostly held by museums, for example the Metropolitan in New York," Unge-Soerling said.

The fact that the frieze was not left in the open has helped preserve the piece from the effects of pollution.

Paint that once adorned the temple has disappeared due to the twin ravages of time and pollution, whereas some traces of paint remain on the piece to be returned Friday, Unge-Soerling added.

The museum displayed the frieze since Wiger-Angner turned it over to the institution in February 2005.

After its return to Greece the piece will feature in a new Acropolis museum currently under construction in Athens.
