PORTLAND — A five-year mystery about the future of the C.W. Parker Four-Row Park Carousel — better known as the Jantzen Beach Carousel — has come to a happy conclusion.Restore Oregon, a nonprofit organization dedicated to preserving historic buildings, announced on Thursday that it has taken ownership of the carousel and is seeking a new, permanent home for the ride.“We have here a wonderful opportunity to make more memories for generations to come,” said Restore Oregon Executive Director Peggy Moretti at a press conference.The Jantzen Beach Carousel was built in 1904 for the St. Louis World’s Fair, and spent some time in Venice, Calif. before becoming a part of the Jantzen Beach Amusement Park in 1928. The park closed in 1970, but the carousel–believed to be one of the oldest and largest of its type in the world–was renovated and installed in the Jantzen Beach Center following the mall’s completion in 1972. It is the last survivor of five large carousels built by the legendary C.W. Parker, who was known as the “amusement king.”When the shopping center was remodeled in 2012, the carousel was dismantled and stored in a warehouse, where it remains today. Later that year, amidst rumors that the carousel would never be reinstalled or had been sold, Restore Oregon added it to its Most Endangered Places list.
