Colonia del Sacramento UNESCO charming city with an interesting historic section jutting into the Rio de la Plata, it was founded by Portuguese settlers 1680 and has the oldest church in Uruguay, Iglesia Matriz, plus Puerta de Campo, Plaza Mayor with the Museo Municipal. Visit the Faro (lighthouse) and go up the stairs for the excellent view. Plenty of Oldtimers in town. Montevideo is one of a handful of capitals where I have not been yet, so there is no comment.
