The Piqua Nuclear Power Facility was an organic cooled and moderated nuclear reactor which operated just outside the southern city limits of Piqua, Ohio in the United States. The plant contained a 45.5-megawatt (thermal) organically cooled and moderated nuclear reactor (terphenyl, a biphenyl like oil). The Piqua facility was built and operated between 1963 and 1966 as a demonstration project by the Atomic Energy Commission. The facility ceased operation in 1966. It was dismantled between 1967 and 1969, and the radioactive coolant and most other radioactive materials were removed. The remaining radioactive structural components of the reactor were entombed in the reactor vessel under sand and concrete.

Pickawillany
Pickawillany

Pickawillany (also spelled Pickawillamy, Pickawillani, or Picqualinni) was an 18th-century Miami Indian village located on the Great Miami River in North America's Ohio Valley near the modern city of Piqua, Ohio. In 1749 an English trading post was established alongside the Miami village, selling goods to neighboring tribes at the site. In 1750, a stockade (Fort Pickawillany) was constructed to protect the post. French and English colonists were competing for control of the fur trade in the Ohio Country as part of their overall struggle for dominance in North America. In less than five years, Pickawillany grew to be one of the largest Native American communities in eastern North America. The French decided to punish Miami chief Memeskia (also known as La Demoiselle or Old Briton), for rejecting the French alliance and dealing with the English traders, which threatened what had previously been a French monopoly over local commerce. On 21 June 1752, the village and trading post were destroyed in the raid on Pickawillany, also known as the Battle of Pickawillany, when French-allied Indians attacked the village, killing Memeskia and at least one English trader and burning the English stockade and the trading post. Following the attack, the village of Pickawillany was relocated about a mile to the southeast. The city of Piqua, Ohio, was established later near this site. Pickawillany's destruction directly encouraged greater British fortification and military presence at other outposts in the Ohio Valley, and has been seen as a precursor to the wider British-French conflict that would become the French and Indian War.

Arrowston
Arrowston

Arrowston is a historic estate in the city of Piqua, Ohio, United States. Built at the end of the nineteenth century for a local industrialist, it has been named a historic site. As the president of the Favorite Stove and Range Company, William K. Boal headed Piqua's largest industrial employer during the Gilded Age and early twentieth century. He and his wife arranged for the construction of the house at Arrowston in 1887, but it was only home to them for about a decade: Mrs. Boal was deeply shaken by the death of one of their sons and no longer desired to live in their mansion, and they moved to a residence in central Piqua in 1898. Later owners expanded the property in 1929, creating a large estate around the house: the newly expanded property included the construction of a lake and canal, as well as extensive other landscape architecture. No major changes have been made to the landscaping since 1929.Arrowston's main house is a three-story building in the Georgian Revival style of architecture. Numerous Neoclassical influences are obvious, ranging from grand themes to small details: the careful symmetry of the whole design, its size in comparison to its surroundings, and the hip roof are typical of the style, as are details such as its ornate cornice, the pilasters, and the conventional double-hung windows. Both weatherboarding and brick are employed in the walls, which rest on a stone foundation and support a tiled roof. Multiple dormers rise from the walls: the eaves at the bottom of the roof extend past the walls, which in some points are extended above the roof, causing the latter to appear notched. Numerous windows are equipped with shutters, while the roof is gabled. Large chimneys form the highest points of the house.Today, Arrowston is surrounded by modern subdivisions, but its extensive landscaping distinguish it easily from the newer neighborhoods around it. Its design is significant to the point that it has been given federal historic site status, being listed on the National Register of Historic Places in early 1980 because of its architecture; besides the house, the designation embraces seven outbuildings and a pair of related structures. It is one of four National Register-listed locations in Piqua, along with the Fort Piqua Hotel, the Piqua High School, and the Piqua-Caldwell Historic District.
