Crystal Cave: Discovered 1871

The History of Crystal Cave

On Sunday, November 12th, 1871, William Merkel and his assistant, John Gehret, were blasting for limestone on a farm owned by Merkel’s parents. At the time, crushed limestone was a valuable resource widely used by farmers to increase the fertility of soil.

To their astonishment, they noticed a dark, narrow hole in the side of the steep hill, eighty feet from Gideon Merkel’s farmhouse. They pulled away the surrounding dirt to reveal an opening large enough to penetrate. Once inside, darkness precluded further exploration.

The news of the potential cave discovery created much excitement in the small rural Kutztown community. Plans to explore this natural curiosity were made that same evening at a local tavern called Lesher’s Bar. Several adventurous neighbors, including John Gehret, went back a few days later equipped with ropes, ladders, coal oil lanterns, and torches. Their suspicions were confirmed. A good sized and well-decorated cave did exist on Gideon Merkel’s farm. Through word of mouth, nature’s silent development in the mountainside suddenly became big news.

A few weeks later, a group of 12 men organized an exploration of Crystal Cave. Once inside the cave, four of the men exited back outside and remained above ground. The rest of the group climbed through the cave for the next 1 ½ hours. They remarked about the sparkling diamond-like crystals that adorned the walls of the cave. As a result, the cavern immediately became known as Crystal Cave.

A local jeweler examined the small sparkling formations and determined they were not diamonds. Early explorers were disappointed by the jeweler’s assessment, however, their disappointment was soon replaced by joy when they realized the considerable dimension of the cave cavity and the abundance of ornate formations.

For the next two months, numerous curiosity seekers entered the open cave at their discretion. Fearful of vandalism and broken formations a neighboring farmer with a passionate hobby for collecting Indian relics and geologic specimens, leased the cave from Gideon Merkel in February 1872. Samuel D. F. Kohler, leesee, immediately erected a rudimentary wooden door to protect the cave from trespassers who could potentially damage the cave. A few years later a more appealing stout door replaced the wooden planks that were initially nailed to the side of the hillside.

No one was allowed inside the cave unless Kohler accompanied them. The next month, 31-year old Samuel Kohler purchased the 47-acre farm,including Crystal Cave, for $5,000, and became Pennsylvania’s first full time cave operator. The formal deed of conveyance was recorded in the Recorder of Deeds Office of the Berks County Courthouse on April 1st, 1873, more than a year after execution of the sale. (Deed Book Volume 492, P. 621-623.)

1872 Early Development

Interest in Crystal Cave was so great that as soon as Kohler leased the property he received word that a committee of men from a newly formed association of scientists, academic professionals, and enthusiasts of natural history were planning to study and report on the recently discovered cave in Richmond Township. They called themselves The Reading Society of Natural Sciences. For years Kohler reprinted their marvelous testimonial about Crystal Cave in various marketing promotions. In anticipation of his grand opening, Kohler labored fastidiously to remove unnecessary breakdown to create a suitable pathway inside the cave. He laid boardwalks and built wooden stairs and railings for safe passage.

He created a cave tour by identifying and naming familiar shapes of animals and other representations typical of the romantic landscape aesthetic movement of the mid-Victorian Era. Initial illumination to emphasize visual scenery came from using kerosene to ignite the walls of the cave and torches made by soaking rages in kerosene. Tallow candles and coal oil lanterns were additional sources of light.

Accessibility up the steep 80-foot incline to the cave entrance was facilitated by a grated path and a vertical series of rock steps. By late May 1872, Kohler announced the Grand Illumination of the Crystal Cave was to be held Saturday, May 25th, 1872. Admission would be $.25.

May 23, 1872 Announcemnet of the Grand Illumination


Samuel Kohler advertised the Grand Illumination of the Crystal Cave, on the front page of the Reading Times and Dispatch Newspaper on May 23, 1872 and also on page 4 the following day. Printed billboards posted at various business establishments also provided notice that the public was invited to the grand opening and illumination of the beautiful Cave and that The Greenwich Cornet Band would provide entertainment. There is no record of attendance that day. This is inconsequential, however, due to the historic nature of the event.

It was not unusual to find limestone caves in this region as Berks County has a disproportionate share of them. What was unusual was the promotion of a natural wonder for profit. Operating a cave for public pleasure in Pennsylvania was a novel concept and was unprecedented at that time. Crystal Cave not only was the first show cave to operate in Pennsylvania but was one of the first tourist attractions in the state.

Kohler continued to focus on relevant marketing details of the day to advertise Crystal Cave. Common forms of advertising in the 1870’s were word of mouth, newspaper advertising, and ephemera such as trade cards, printed billboards and broadsides, and postcards. Trade cards were a cheap, colorful and common form of Victorian advertising. Typical trade cards had a picture on one side and an ad on the other and were considered to be the TV commercials of the day.

1886 – David Kohler


Samuel’s son David was twelve years old when he became a tour guide and driver of the stagecoach that transported tourists. On November 2nd, 1886, at the young age of 21, David purchased the tract of land known as “Crystal Cave” from his father for a sum of $4,300. (Deed Book Volume 170, page 394.)

David continued the pursuance established by his father of publicizing and creating interest in the increasingly renowned natural curiosity. Local artists, photographers, scientists, members of the Berks County Historical Society, and Professors of higher education were encouraged or invited to come to Crystal Cave in the anticipation of resulting free publicity.

On October 15th, 1919 Marion Kurtz and Francis Finley were united in marriage beside a floral decorated natural alter inside of Crystal Cave. A piano carried inside the cave provided musical accompaniment. Several hundred people arrived that day to wish the newlyweds well. It was the first time a wedding had been performed in a cave in Pennsylvania. The unusual nature of the nuptials provided a substantial amount of free publicity, as it was front-page news in both the Reading and Kutztown newspapers. For years David Kohler sold postcards of the couple on their wedding day at Crystal Cave.

Crystal Cave Company Inc


In 1923, at the age of 57, David Kohler was ready to retire and sold his interest in Crystal Cave to the present owners who formed Crystal Cave Company, Inc. The Company instituted a massive revitalization effort both below and above ground with the objective of maintaining integrity of the cave. Tons of concrete were required to rebuild steps and pathways inside the cave. Railings and metal bridges were installed for safety consideration. In 1927 a massive lead cable connected to metal reflectors replaced the delco battery pack lighting system. Large dome lampshades were installed subsequently.

Other improvements to the property included building and macadamizing roads and creating parking lots, constructing a prominent stone entrance to the cave in 1935, planting several hundred thousand evergreen trees, and creating a picnic park.

Despite the passage of time today’s tourists are intrigued in the same manner as early visitors were in the 1800’s. With the exception of easier access, illumination and slightly different names to identify formations, Crystal Cave’s appearance and description is very similar to when it was a newly discovered cave. In 1876, William H. Egle M.D. stated in his book An Illustrated History of the Commonwealth of Pennsylvania, Civil, Political, and Military “that Crystal Cave is a remarkable curiosity and a subterranean wonder regarded with admiration by all who examined it”.
