in 1861. Named after a patron saint of Bohemia, the sanctuary's construction began in 1871 and was finished in 1874. Because of the church's small congregation, St. John's did not support a resident priest. Instead, a Chicago-based priest would visit the congregation once a year; for the rest of the year, Bohemian-speaking members of the church would conduct services. While St. John's stopped hosting worship services in 1914, the cemetery remains open to this day. In 1900, Edward and Francis Konopasek (a Czech couple after whom one FRG's wards is named) built the Grove's first hotel—the Hotel Fox—and established a taxi service that shuttled notables like the Chicago Mayor Anton J. Cermak and Illinois Attorney General Otto Kerner Sr. from the nearest train stations to the Grove. FRG was once also home to a Czech-styled castle replete with 100 stained glass windows. It was built by John Legat Sr. in 1920, but most of the castle is now dismantled. Resort town period Starting in the mid-nineteenth century, Czech immigrants transformed the Grove from a backwater pioneer settlement into a resort town. Chicagoans were attracted to the Grove's waterfront and surrounding hilly woodlands. Staying in establishments such as the Hotel Fox, Chicagoans traveled to the Grove via the Illinois & Wisconsin Railroad station and livery bus shuttle in neighboring Cary, Illinois. Picnic Grove heyday In 1899, Eman Opatrny bought his father Frank's homestead and converted it into picnicking grounds. Known as the Fox River Picnic Grove, this large swath of land housed picnic plots (including sheltered areas), a shooting gallery, a horse track, six bars, a boathouse, boat docks, a dancing platform, a restaurant, a photo gallery, rowboat rentals, a bowling alley, a railroad spur track, a steam-powered excursion boat, and baseball diamonds. Trainloads of pleasure-seekers would pour into the park for weekend getaways. Opatrny also built many cottages near the river's edge. The Picnic Grove suffered a major blow in 1918 during a fire; most of the attractions from the early 1900s were lost. In 1942, Louis Jr. and Clara Cernocky purchased the Picnic Grove. The couple added more amenities, including a new dance pavilion, an air-conditioned cocktail lounge, and a 300-foot sandy beach. It fell into disarray in the 1960s. The Grove Marina, opened in 1961, was an entertainment center that included a restaurant and a cocktail lounge with live entertainment, but was destroyed by yet another fire in
