I had the privilege of visiting Vienna with Priyanka last month. I got to relive the months I spend in Vienna between 2012-13. It was a very relaxing trip. We got to enjoy taking a bunch of photos, and do a bunch of other touristy thing I hadn't done before.
In 2013, the Virgilkapelle (Vergilius Chapel, an unground crypt and chapel) was still being unearthed and prepared for exhibition. On this visit, we were able to see it. It was nothing remarkable but it's story is strange and mysterious.
We also visited the Clock Museum, and the Ducal Crypt below Stephansdom (St. Stephen's Cathedral). The crypt is the home to the remains of departed Viennese royalty, Catholic clergy, and victims of the black death.
