What is the oldest building still standing?

Japanese archaeologists have uncovered the remains of what is believed to be the world's oldest artificial structure, on a hillside at Chichibu, north of Tokyo. The shelter was built by Homo erectus, an ancient ancestor of humans, who is known to have used stone tools. The site has been dated to half a million years ago. It consists of what appear to be 10 post-holes, forming two irregular pentagons which may be the remains of two huts. Thirty stone tools were also found scattered around the site. http://www.science-spirit.org/archive_cm_detail.php?new_id=283 Jul 18 06, 6:11 AM

The homo erectus building in the previous posting is not still standing. One candidate for oldest building still standing is Knowth Passage Tomb, in Meath, Ireland, which dates from about 3200 BC. Jul 18 06, 7:27 AM

Another possibility: The temple of Ħaġar Qim excavated for the first time in 1839, dates from the Tarxien phase (c.3200-2500 BC). http://en.wikipedia.org/wiki/ĦaÄ¡ar_Qim Jul 18 06, 8:58 AM

Stonehenge is most definately still standing, and rather spectacularly too. And is around 5,000 years old. http://en.wikipedia.org/wiki/Stonehenge Mar 26 08, 7:01 PM
