Ashtabula High School was a public high school that served the city of Ashtabula, Ohio from the mid-1800s[2] until it was closed in 2001 in order to merge with nearby Harbor High School under the name of Lakeside High School. The building then housed 10th-12th grades until the new Lakeside was completed in 2006. The latest edition of AHS (built in 1916) was demolished in 2012.[2]
