This is the first time in 15 years that so many of these high-masted ships have called on Savannah's port.

They're here for the Tall Ships Challenge, sponsored by Tall Ships America, a nonprofit that focuses on youth education, leadership development and the preservation of North America's maritime heritage.

Through this weekend, visitors will get a chance to tour the vessels, go on cruises and learn about how shipping and travel took place long before the invention of the first steamship (which sailed from Savannah, by the way).

Films, lectures and music are also part of the weekend's activities, although picture-taking seemed to be a priority of most River Street visitors on Thursday and Friday.

These photos were provided by Visit Savannah, the city's tourism agency.
