It is uncertain where it was first discovered that a combination of hydrated non-hydraulic lime and a pozzolan produces a hydraulic mixture (see also: Pozzolanic reaction), but concrete made from such mixtures was first used on a large scale by
Roman engineers.
Many excellent examples of structures made from these concretes are still standing, notably the huge monolithic dome of the
Pantheon in Rome and the massive
Baths of Caracalla.
The vast system of
Roman aqueducts also made extensive use of hydraulic cement.
Some (existing) cultures have remains. See pictures above.
Some nonexisting ones have, too. See pictures below. Sorry, I didn't find older ones than 19th century.

Brigham Young Nauvoo Home
Nauvoo, Illinois
Visit the home of Brigham Young, the second President of the Church of Jesus Christ of Latter-day Saints, leader of the Church's movement to the West, and first territorial governor of Deseret, later named Utah.
Constructed from 1843-44, this brick home provided a dwelling for Young's family of seven children and
his wife, Mary Anne.
or the Lion's house for
his very large family:
The Lion House was built in 1856 by Brigham Young in order to accomodate
his very large family. It gets its name from the statue of a lion over the front entrance, made by William Ward. The lion design is modeled after one located at a prominent home in Vermont where Brigham Young spent some of his childhood.
The House was partly designed by Truman O. Angell, who also designed the Salt Lake Temple, and was built with adobe and sandstone which came from City Creek Canyon.
(Adobe? Cement, if I may ask!)Before its use as a reception and banquet center, the Lion House was used, of course, as Brigham Young's home, as a home economics center for Latter-day Saint University, and a social center for the Young Women's Mutual Improvement Association.
by the way using the
Lion House as a social center for the Young Women's Mutual Improvement Association ...
Fine. Or brutal. Please take your pick.
