Lakeside is a private community and census-designated place in Danbury Township, Ottawa County, Ohio, United States, on the shores of Lake Erie. It is one of only a few continuously operating Independent Chautauquas that persist in the 21st century. Located just west of the village of Marblehead, the community is approximately one square mile in size. The entire community is listed on the National Register of Historic Places as the Lakeside Historic District.
The Lakeside Association made the decision early on to sell plots of land within the community on renewable 99 year leases. Over the years, residents built cottages and houses on their plots. Almost all of the cottages are unique; many are wood houses in Victorian style, although different styles of buildings and materials can also be seen. Restaurants and shops also opened around the downtown park of Lakeside.
Lakeside contains many well preserved historic buildings. In 2001 Chris Thomas documented all the homes and buildings within the gates of Lakeside, and counted a total of 890, although more have been built since then along the Oak Avenue extension and still others as in-fill projects. The community is largely residential with a small business/shopping area near Central Park. There is also a small local museum, Heritage Hall, at the corner of Maple Avenue and Third Street.
The Hotel Lakeside was built in 1874 and is open from Memorial Day to Labor Day. After Labor Day through October, it is open to private groups only. The Fountain Inn, on the other hand, is open all year. A more modern hotel, it has conference facilities as well. There are many privately owned cottages available for rental through local real estate offices, in addition to smaller bed and breakfast inns.
