The Ohio River facing East. Louisville has a large waterfront as the city sits in a bend of the river.

The Louisville Slugger Museum in the West Main district includes a factory tour and a free mini slugger which is much smaller than the world's largest bat outside. Make sure to go on a day with bat production to get the most of the tour.

The above/left five photos are from the West Main district of downtown, known for its cast iron facades. This is a good walking area with a number of museums and various galleries.
The two photos above are from the Zorn Ave Water Pumping Station which now houses the Louisville Visual Arts Center. There is also some handy riverfront picnic tables and a large expanse of grass for kites and such.

The last remnants of the now much revitalized downtown. The classic cast iron facades are still preserved though and ready for new buildings to match.
