|This 20 acre point on Lake Union was cleared in 1906 to construct a plant to manufacture gas from coal - later converted to crude oil. Import of natural gas in the 1950's made the plant obsolete. The city acquired the site for a park in 1962. The park was opened to the public in 1975. The boiler house has been converted to a picnic shelter with tables, fire grills and an open area. The former exhauster-compressor building, now a children's play barn, features a maze of brightly painted machinery.
