Across major cities around the globe, high-rise apartment buildings are a mainstay of the modern urban skyline. But convenient high-rise, high-density living isn't something new.

In this eye-opening program, host Michael Guillen explores how the ancient Romans inhabited multistory apartments more than 2,000 years ago. Travel to the Roman seaport of Ostia, where a number of these ancient apartments still exist. Like their modern descendants, these apartments provided more than just places to live - offering baths, cleaners, and restaurants, all housed in complexes that were several stories high. Next, in bath, England, take a fascinating tour of the brilliantly designed Roman baths. And finally, watch as Michael performs as intriguing demonstration of how ancient dry cleaners, known as "fullers," cleaned garments with human waste.

Featuring expert commentary and the latest in computer graphics, Ancient Rome: The Rise of Apartments is a captivating look into the earliest in apartment living.

What made Roman concrete so great?
It's all about the seawater. The ancient Romans mastered concrete more than 2,000 years ago and used it to build piers, breakwaters, and other structures. Despite the batterings of time and seawater, some of those structures still stand today. In fact, their concrete has grown stronger over time — the result, scientists now say, of complex interactions between seawater and volcanic ash used in the mortar. "The Romans had a very different framework for making the cementing fabric of their concrete," says University of Utah geologist Marie Jackson, lead author of a report on the concrete published recently in American Mineralogist. She explains that for ancient concrete makers, the first step was to mix volcanic ash with lime and water — fresh water for architectural monuments, and seawater for marine concrete. (Chunks of volcanic rock were also added to the mortar as aggregate.) "This produced a very potent reaction, called a pozzolanic reaction, that created a really robust framework of coherence in the concrete," Jackson says. But in the recent research, Jackson and her colleagues were interested in something that seemingly occurred later, long after the concrete was cured. In samples of Roman harbor concrete, they found the minerals phillipsite and aluminous tobermorite. They were particularly interested in the presence of tobermorite, a rare mineral with interlocking, plate-shaped crystals. "We found that tobermorite grows through the fabric of the concrete," Jackson says. "This is a platy mineral that has some very important industrial ... applications, but we have a great deal of difficulty making this mineral."
