Luxembourg a run for their money.
The end of our trek was the Russian Orthodox Cathedral. One of the cool things about this trip was getting to see these Orthodox churches. They are so unique and different compared to the churches in western Europe.
We passed by the "Three Brothers," a trio of the oldest surviving houses in Riga. The oldest, white house has minuscule windows dating from the 15th century when taxation was based on window size. The yellow one is newer from 1646, and the green narrow one is the newest from the turn of the 18th century.
Here's another shot of the darling Town Hall Square for good measure.
