📱 1 to 10 phones · 1 team per phone · Independent codes
In the late 1800s, as Pennsylvania authorities moved to erase Pennsylvania Dutch language and culture from schools and public life, something extraordinary happened in Lancaster County
You are an archivist for the Commonwealth of Pennsylvania, dispatched to Lancaster in 1780 to decipher an ancient code hidden within the city's urban fabric.
Your mission begins in front
Uncover the forgotten symbols of Lancaster, a Pennsylvania city where colonial history intertwines with the mysteries of Hex Signs.
« For the King, the Law, and the People »— Official motto of the city of Lancaster
Your Hex Sign quest begins in the heart of Lancaster, in front of the Central Market House. This building, constructed in 1730, is a living testament to the city's commercial history, housing over 60 stalls across 6,500 square feet. Continuously open on Tuesdays, Fridays, and Saturdays for three centuries, it was listed on the National Register of Historic Places in 1977. By observing its bricks and arches, you begin to perceive hidden patterns, echoes of the first settlers of the Pennsylvania Dutch Country, and the whispers of the merchants who shaped this square.
The path then leads you to the Demuth Museum, at 120 E King St, a house dating from 1810 converted into a museum in 1981. This site is dedicated to the modernist artist Charles Demuth (1883-1935), with over 200 of his works on display, offering insight into Pennsylvania art. Located in the historic King Street district, just 300m from the Central Market, this place reveals how artistic traditions and innovations intertwined in Lancaster, with each canvas potentially hiding a clue about the symbols you are seeking.
Your exploration continues to LancasterHistory, at 230 N President Ave. This 1914 villa houses a museum and historical library with a collection of over 20,000 artifacts documenting the history of Lancaster County since 1730. The site also owns the Wheatland estate of James Buchanan (1791-1868), the 15th President of the United States. 500m from the starting point via N Duke Street, this stop immerses you in the archives, where the city's secrets and the origins of Hex Signs are sometimes recorded in old parchments.
As you head towards Penn Square, you cross Binns Park, a small public space developed in 1976 at 234 N Queen St. This park, named after the 19th-century Quaker merchant Thomas Binns, offers a resting spot with its sculptural fountain. It is located near Queen Street, a main thoroughfare of the route that brings you back to the city's historic core. It is on Penn Square, created in 1730 and surrounded by 18th-century buildings like the Lancaster County Courthouse built in 1794, where public gatherings and major political speeches took place, shaping Lancaster's identity.
Your quest for Hex Signs culminates on Penn Square, in front of the Lancaster County Courthouse, a neoclassical edifice completed in 1853. Its 160-foot dome, inspired by the Pennsylvania State Capitol, dominates the square. This seat of the county courts since 1853, housing judicial archives from the 18th century, was listed on the National Register of Historic Places in 1974. By solving the final puzzle, you understand Lancaster's role in Pennsylvania's history and the profound meaning of the city's motto, “Pro Rege, Lege, et Grege” – For the King, the Law, and the People – which still resonates in its historic streets, anchoring your discovery in the heritage of the National Register of Historic Places.
