The park covering the area of 9 acres includes many open-air statues and a beach. It was designed by the architectonic company Weiss/Manfredi. The park is administrated by the Seattle Art Museum. As a freely accessible park with permanent as well as temporary exhibitions, it is a unique institution in the United States. The maintenance of the statues is a frequently discussed issue, especially among experts. The statues stand near the ocean and are endangered by salty water and water animals. The water causes problems especially to the wooden statues as salt easily penetrates the material and is quite aggressive. The high painted statues, such as the Alexander Calder's "Eagle", are damaged by bird droppings. The maintenance of the statues is very expensive but absolutely necessary for their preservation.
The most significant artists of post-modern and contemporary sculpture exhibit their art pieces in the park. The statue called "Typewriter Eraser, Scale X" was designed by Claes Oldenburg and Coosje van Brugen. It was placed in the park in 2009 and it is a part of a series of objects of everyday use in over-dimensioned scale. Another important artist, whose work is presented in the park, is Richard Serra. His "Wake" continues the experimental projects aiming to re-define public space. Elsworth Kelly is a significant representative of geometric abstraction art and he has contributed to the park with his piece "Curve XXIV". One of the best-known statues of the open-air gallery is the "Eagle" by Alexander Calder. The park nicely combines the most interesting statues from the 20th century from all over the world and the calm of the adjacent beaches.
