Nagyvásártelep is the longest building I've entered to date, with a mind boggling 243 meters in length, with 18 arched roofs. It is a former wholesale market built in the 1930's and located in South-East Budapest. The hall hosts an impressive show of artwork.
Next door is the office building, which was just too spooky to visit alone. In the main hall, I had an unnerving encounter already, as a young guy seemed to be circling around me in the building & sometimes it's best to make a swift exit.
