Atlantic City Mercantile

The Atlantic City Mercantile is a one-story building of adobe blocks covered with tin siding, standing on a stone foundation with a full basement. A false front on the south side hides a gabled roof, and the front facade has large display windows and a formed metal cornice. The interior walls and ceilings are also covered with tin.

Lawrence Geissler, a German immigrant who had come to Wyoming at 18 as a cowboy, built the store in 1893, four years after opening a shop on land owned by mining speculator Emile Granier; he bought the property in 1900 for five dollars. The store housed the town's telephone exchange and post office and closed after Geissler died in 1929. Lyle F. Moerer reopened it as a tavern in 1964, keeping the store's name and appearance.

The store also housed Atlantic City's telephone exchange and post office, making it the point where residents connected with the outside world. Lyle F. Moerer reopened it as a tavern in 1964, keeping the store's name and appearance, and it has since been profiled in National Geographic and Esquire.

The site is best explored on foot due to its compact layout and narrow streets. Visitors should come prepared, as Atlantic City is very small with limited services; bringing supplies and planning ahead is wise, especially if staying overnight.

The building's walls and ceilings are lined with tin, and a false front hides its gabled roof. It was listed on the National Register of Historic Places on April 25, 1985, and has appeared in National Geographic and Esquire.
