The Delphi site and museum is worth a visit in Greece. The modern town of Delphi is a few hundred metres up the road from the ancient site. After the noise, heat, dust and crowds of Athens, the town was quiet, cool and clean.
The Delphi Archaeological Museum was refurbished in 1999 and looks much less cluttered than many in Greece, with a few important pieces given the space they deserve. The museum is a little too prominent, intruding on the ancient ruins behind.
The most evocative part of the site for me was the gymnasium with the floor of the stoa (covered walkways) and track still recognisable.
In a sense Delphi has not changed its role in several thousand years, having started and remaining a tourist attraction, due to the location and fame. The sacred way is lined with the remains of treasuries where the pilgrim's offerings were stockpiled. About the only difference is that the offerings are now taken in the form of Euros and credit card payments.
