Colonia del Sacramento, located in southwestern Uruguay is one of the countries oldest with a population of 27,000. Between Portugal, Spain, Brazil and the UK, it has changed hands a dozen times. It is renowned for its historic quarter, a World Heritage Site. Nicolai and I took the ferry from Buenos Aires for a brief visit this afternoon. It was a nice departure from the hustle and bustle of BA if not the heat and humidity. We made a leisurely walking tour of the tree lined streets and enjoyed a late lunch/early dinner on the waterfront.
