Mallory HouseBomberger Park
Bomberger Park in St. Anne's Hill was lost to urban renewal. It still is home to a park, but has lost the elegant arbors and waterways.
The Classic Theatre
The Classic Theatre on West Fifth Street was demolished in 1991 after sitting vacant for many years. It's grand ballroom and marble floors were a favorite for the African-American community in Dayton in the first half of the 20th century.
The 1888 French Gothic Romanesque public library
The 1888 French Gothic Romanesque public library at the corner of Third and Patterson was made of Dayton Limestone and Marquette red standstone. It was torn down 1962 after migrating the library to it's new headquarters next door.
Union Terminal
Union Terminal was built in 1900 and was a bustling center of activity for 40 years. It was demolished in the 1960's near the time of the demise of Robert Boulevard.
Historic Dayton Churches
Many Dayton churches are threatened by changing times and diminishing congregations. Shown are two churches that were torn down over the last five years. One on St. Clair Street (left) and the other at the corner of 6th and Brown in the Oregon Historic District.
The Rikes & Wilcon Canal Building
In 1999 we said good-bye to 2 large pieces of Dayton history. The Rikes (Lazarus) building (directly below) came down with a boom as it was imploded in November to make way for a new performing arts center. The 19th century Wilcon Canal Building (far below) was once the most endangered structure on the PDI list. It fell victim to fire in the early months of 1999.
Steele High School
Built in 1894, Steele High School was home to all of Dayton's high school students until 1906. The wood structure was enormous and costly to maintain. It closed it's doors at the southeast corner of Monument and Main Streets in the late 1930's and was demolished in the late '40's.
Canby House
The 26-room Canby House in Grafton Hill was demolished in 1988 to make room for a parking lot for the Greek Orthodox Church, after the 1915 structure was renovated the year before as a designer showcase house.
Lakeside Park
Lakeside Park was built in 1890 and was upgraded in the 1920's to include some of the country's most impressive amusement rides, made by the nation's largest manufacturer of amusement rides, National Amusement Company, right here in Dayton. The park was very popular until 1967. What was left of the park was destroyed in 1994 to make way for U.S. 35.
