Here are some photos i took the other day when we walked over to the bus station to meet a friend. The first five are all from the Plazuela Ecuador and around and then the next five are from along Avenida Pedro Montt (the street on which the nasty Congreso Nacional sits).
There are some gorgeous buildings between Plaza Victoria and Avenida Argentina. Most tourists will never see them, unfortunately, as the whole area just isn't particularly tourist friendly-no bathrooms, no decent cafes or restaurants and a slight edge to it. There are a couple of great markets there to get fresh fruit, veg and seafood and if you're looking for car parts then it's the place to go...but for a nice, relaxing, touristy stroll...maybe on Sundays...but not during the week.
Ornate exterior plaster-work isn't really very common in Valparaiso, nor in Chile in general (especially when compared to Argentina). This building is one of the prettiest i've seen here and the door is the best i've seen in Chile.
