This cache is placed across from St. Lomans Hospital. The hospital is a freestanding 41 bay, 3 storey psychiatric hospital built circa 1855 and extended circa 1895. The hospital is a well-detailed Victorian institutional complex, with Gothic style extensive Tudor Gothic detailing. The structure was built to designs by J. S. Mulvany (1813-1870), possibly the most celebrated architect operating in Ireland at the time. It was opened in 1855 and cost some £35,430 (equivalent to €44,986 in today's money) to build. It was built to accommodate 300 patients and the first patients were transferred from The Richmond Hospital in Dublin, all of them female.
In March 2015, the hospital went under lock down when a package was handed to the administrative staff of the hospital. When opened, mysterious white powder was discovered along with a note saying, "ISIS is going to get you". The chilling message and contents of the package immediately sparked a major alert. Gardaí were called and quickly moved to seal off the main building - which houses only administrative staff - amid concern of a biological or chemical threat. A cordon was put in place and traffic diversions implemented around the hospital, which is located to the north-east of the midlands town. The army disposal unit from Athlone arrived to the building to examine and dispose of the substance. However, it was soon discovered to be a hoax, but the Gardaí were still on high alert.
