In ancient Rome, what was the name of the first public bath?

The Baths of Agrippa (Latin: 'Thermae Agrippae') was a structure of ancient Rome, in what is now Italy, built by Marcus Vipsanius Agrippa. It was the first of the great thermae constructed in the city, and also the first public bath.

In the bath's first form, completed in 25 BC, it was a hot-air room also known as a "laconian sudatorium or gymnasium". With the completion of the Aqua Virgo in 19 BC, the baths were supplied with water and with the addition of a large lake and canal.
