My second day in Vilnius, after visiting the Lithuanian Archives in search of my family history, I again met Pedro in the afternoon and he showed me around. We walked to the Gediminas Tower, or specifically, Gediminas Tower. It is the last standing part of the Upper Castle, which is what remains of Vilnius castle complex, hoping to get there while it was still open.
For speed, we opted to walk around to the front, the river side, and took the funicular, then walked down.
These are some of my photos of the castle remnants.
