The City Mayor's Office announced a program for the large-scale rehabilitation of public premises, and renovation of the city, which included the reconstruction of the Fő square.Permit plans have been completed in the same year. With the design of the reconstruction, architects Mezei Építész Műhely and the Timpanon Mérnökiroda were commissioned, while construction was delegated to the Boroszlán Zrt., and the plans were completed in June 2009. Permit plan of the ice-rink was completed in 2008, the execution plan was completed in 2009. By the original plans, the surface of the trapezoid-shaped ice-rink was 1,400 m2. Because of the excavations of the sights, the fountain and the entry to the church, the surface of the ice-rink was reduced. Direction of the cooling pipes was modified to perpendicular compared to the original plans. The new plans were completed in February 2013. Installation of the cooling pipes of the ice-rink of the Fő square was completed in May 2013. The City Skating-rink of Pápa is in the middle of the Fő square, surrounded by old monuments.

The ice surface is 950 m2, required cooling power is max. 240 kW. The cooling system can maintain the ice in excellent quality in rain-free conditions, in case of slight wind or calm, and diffused sunlight, up to +15 °C outdoor temperature. In rain, wind or sunshine the ice is still suitable for sports up to +20 °C. The season of the ice-rink is from end of October till the beginning of April, with the exception of some warm days.
The cooling system of the ice-rink consists of three parts:the cooling system providing the cooling energy,the pipelines of the intermediate mediumthe pipe system of the ice-rink.
Required cooling power for the cooling of the ice-rink, the freezing of the ice and for keeping it cool, is provided by the cooling system installed in the power-house and outside in the yard of the building block. The cooling system is a single-stage system, operating with chlorine-free cooling medium mixture (blend), cooling the intermediate medium (ethylene-glycol). The power-house, which is placed in the cellar of the house of 7 Fő street, is cooling down the intermediate medium with a rotary s
