Taking its cues from the Aerosmith classic, the Preservation Alliance asks but one thing of its fellow Philadelphians this weekend - walk this way.

Already three weeks into its Architectural Walking Tours series, the alliance will host three more installments beginning tomorrow, allowing participants to take in the sights, sounds and structural designs of local neighborhoods under the tutelage of seasoned guides.

Interested parties can join the tour directors - namely, historians, architects, and city planners working as volunteers - at 10 a.m. tomorrow in the center of Rittenhouse Square, later at 2 p.m. on the steps of the Bellevue, 200 S. Broad St., and at 2 p.m. Sunday in Haddonfield in front of the Haddonfield Historical Society, 43 Kings Highway East.

"These tours have been going on in Philadelphia for many, many years," said Elise Vider, the alliance's deputy director. "We cover areas of interest that are important, that have a great story to tell in terms of their buildings and in terms of their history."

Tomorrow afternoon's survey of the Broad Street area will illuminate the city during the Gilded Age. Beginning at the Bellevue, an emblem of urban opulence since its opening in 1904, the walk moves toward the lavish townhouses and mansions inhabited by the glitterati of the late 19th century.

"Everyone always thinks about the colonial history [in Philadelphia], but we really came into our own in the Victorian era," Vider said. "There was some extraordinary architecture that went with that."
