St. Florian's Gate was just 1/2 block from our hotel in Krakow. The permit to build it was issued in 1285. It was part of the medieval city walls. Here's the wikipedia article and here's my picture of the gate.
Just north of the gate is the Barbican of Krakow, built around 1498. Here's the wikipedia article on it and here's my picture.
If you zoom out 3 clicks, you can see the park area that was built where the old wall was torn down.
We had a layover in Vienna on our way to Krakow so we jumped on the subway and went into town. We hadn't done much research so we just went to the center of the city and walked around. We came out near St. Stephen's Cathedral. The last section of it was finished in 1511. The south tower is 445 feet tall, 343 steps (trust me). 343 is 7 x 7 x 7. The north tower is only half as tall, at 223 feet. A word to the wise, the observation deck is on the north tower!
Here's the wikipedia article and my pictures begin here. Vienna's web site is here.
Martha's Vineyard is just full of surprises. As we rode our bicycles around Oak Bluffs we came across Trinity Park.
Trinity Park is a Methodist Church campground. Around the tabernacle in the center of the park, the faithful have built gingerbread cottages. It's mentioned in the wikipedia article here. There's an interesting walking tour here.
