"Stairways and Surprises: A glimpse of Astoria: 1890 to 1925" is the theme of Clatsop County Historical Society's 2003 Historic Homes Tour, held from 12:30 to 4:30 p.m. Sunday, Aug. 10.

Begun in 1966 as a fund-raiser for the society, the self-guided tour has been held nearly every year. At least one of these homes has never been open to the public before.

The tour includes six Astoria homes built between 1890 and 1923. At each home, tourists will be greeted by a historical society member and the current owner of the property. The historical society will provide a map and history about each of the chosen sites. Cost of the tour is $10.

A pretour lunch is held on the Flavel House grounds beginning at 11:30 a.m. Tickets for the sack lunch may be purchased in advanced or on the day of the event. Ham or turkey sandwiches are available. The cost is $6.50.

Advance tickets may be purchased at The Heritage Museum, 1618 Exchange St., Astoria; The Flavel Carriage House, 444 Eighth St., Astoria; Cannon Beach Outdoor Wear, 239 N. Hemlock, Cannon Beach; Vista Sea Cafe, 126 Broadway, Seaside; and A Great Shop, 576 Pacific Way, Gearhart.

People seeking more information or who are interested in having their home open next year, may call Lisa Studts at the historical society (503) 325-2203.
