Author David B. Williams will discuss his book "Seattle Walks" and examine Seattle's history and architecture as seen during walks throughout the city from 7 p.m. to 8:30 p.m. Wednesday, March 1 at the Central Library, 1000 Fourth Ave., Level 1, Microsoft Auditorium, 206-386-4636.

Library events are free and open to the public. Registration is not required. Parking in the Central Library garage will be available for $6 after 5 p.m.

Williams will discuss how Seattle has changed over time, how the past has influenced the present, and how nature is all around-even in an urban landscape. The walks he will cover vary in length and topography, and include both well-known areas and hidden sights of the city. While most are loops, there are a few one-way adventures with an easy return via public transportation. Ranging along trails and sidewalks, the walks lead to panoramic views, intimate hideaways, architectural gems and beautiful greenways.

Williams is a freelance writer focused on the intersection of people and the natural world. His most recent book was "Too High and Too Steep: Reshaping Seattle's Topography," which won the 2016 Virginia Marie Folkins Award, given by the Association of King County Historical Organizations to an outstanding historical publication. Other books include "Stories in Stone: Travels Through Urban Geology" and "The Seattle Street-Smart Naturalist: Field Notes from the City." Williams is coauthor of "Waterway: The Story of Seattle's Locks and Ship Canal." He lives in Seattle and continues to explore and travel through the city by foot and by bike.
