The Olympic Equestrian Center at Markopoulo, also subject to a presidential decree, has been handed over to HOP. The basic works in the area have been finished and uses have been determined. The presidential decree provides for the construction of a hotel and stores, allowing for the development of money-generating activities, which will help in maintenance and operating costs. The local authority and residents in the area have asked questions related to the surroundings, since the area boasts a number of quarries which pose a number of problems, both environmental and aesthetic. The development of the whole area posits the closure of the quarries, they say. A special development scheme for the area stipulates four planning zones, which, besides the Olympic Equestrian Center, will sport hostels, hotels, shops, restaurants, canteens, meeting halls, social welfare buildings, and car parks.
