Thousands of visitors have been attracted by a mysterious crop circle since it was spotted in a Bavarian wheat field last week.

The circle in Raisting, upper Bavaria, has a diameter of 246ft and is formed of three rings.

It was discovered last week by hot air balloonists and word quickly spread through internet forums of the find.

“They sang, danced, played guitar… and slept in the field,” a woman who lives nearby said of the area’s new visitors to the site, the Süddeutsche Zeitung reported.

Farmer Christoph Huttner, who owns the wheat field near Weilheim, told the dpa news agency Tuesday he didn’t create the circle himself.

Christoph Huttner suggests students on summer holiday may have cut the image into his field.

The news agency says thousands of visitors have come to sing, dance and even swing pendulums in the giant image.

Christoph Huttner says he’s not yet sure whether he will leave the circle in his field.
