Mark Zuckerberg and Priscilla Chan visit Parthenon in Athens

The founder and CEO of Facebook Mark Zuckerberg and his wife Priscilla Chan on Friday posted a selfie taken in front of the Parthenon on the Athens Acropolis with the caption: "Celebrating 7 years of happy marriage at the temple for the goddess of wisdom." The couple are on a private visit to Athens.

One of the comments below suggested that Zuckerberg "create a replica of this 2 hrs away from your office in California and make a Athens style new city to make it a head-office for Chan Zuckerberg Initiative."

In a post marking Mother's Day on May 12, the couple had posted a selfie of the two of them taken in front of the Louvre Museum in Paris.
