Athens is a relatively easy Par 2 on the Global Scavenger Hunt, now midway through the 23-day around-the-world mystery tour. We have just 30 hours here, but our visit will largely be shaped by the celebration of the Greek Orthodox Easter (we seem to be hitting all the destinations on a religious holiday). We arrive on the Greek Orthodox Good Friday and one of the challenges is to experience the distinctive celebration. It’s hard to miss. Every church has a similar ritual. I walk down from the Grand Hyatt Hotel where we have arrived in the midday, to the Plaka, stopping to reflect on Hadrian’s Arch before I take the narrow street that leads me to the 11th century Byzantine church, where devotees are coming.
