Coal Palace

The Coal Palace was an exhibition building in Ottumwa that combined Byzantine and Gothic architectural styles with a central tower as its focal point. The structure measured approximately 230 by 130 feet and featured a working coal mine beneath the main floor where visitors could observe mining operations.

The building was constructed in 1890 and received coal donations from ten different Iowa counties for its walls. It became a symbol of the coal mining industry and the economic importance of this resource to the region during that era.

The interior displayed ornaments celebrating local crops and crafts, while display cases showcased goods from regional businesses and manufacturers. The decoration reflected the economic diversity of the area and made the place a gathering point for merchants and tradespeople.

The best time to visit is during dry weather, as the underground coal mine becomes easier to access and details are more visible. Appropriate clothing is recommended, since temperatures below ground are cooler than above surface.

The building was constructed entirely using coal sourced from mines across ten different surrounding counties, creating its distinctive exterior. This choice of materials made it a tangible monument to the local mining industry and attracted visits from national leaders.
