¡Una aventura virtual!

Here are a few sites that will have images for your project:

Images on Britannica Online (enter keywords for your search and then look for the multimedia links on the right side of the article).

If you do search the internet, or use Google Images, be as specific as possible. Search for the names of specific historic sites, churches or points of interest. If you search only by the name of a city or region, you are more likely to discover things you really don't want to see (you know what I'm talking about!).
