Mausoleum of Hadrian / Castel Sant'Angelo #1

The day when we visited the castle was a special day; most of Roman museums and monuments for tourists were admission free.
So, there was a very long waiting queue for the entrance of Castel Sant'Angelo.

We waited at least one hour, or maybe more than one, before entering Mausoleum of Hadrian.

We killed time by talking with a girl who was waited in front of us among the waiting queue.

She was a Swiss, single, working for a company which dealt medical optics,  her parents bought her a canon EOS digital camera, and so on and on.

Talking with other tourists became one of good travel memories as well as visiting historical monuments.
