Archaeologists have uncovered an old Roman-era colossal complex from the second to third century AD near the city of Reims in northern France.

The construction comprises of two porticoed halls 65 ft lengthy forming the arms of a U.

The galleries house more than 20 rooms, ranging from hallways to living rooms with fireplaces and chalk-flooring.

Nine of the chambers had previously been conventional baths.

A large number of the pilae stacks (square tile piles) that supported the ground are still in place and are in fantastic condition in 5 of them, which had a hypocaust underfloor heating system.

Two rectangular stone constructions that may have once been a part of the backyard are located inside the empty home in the space between the galleries.

A fountain or basin was one of several two.

Two pressurized water pipes that filled the basin and/or supplied the water function had been found.

Decorative painted plasters with floral designs were found by archaeologists.

Some of the pigments utilized, including a "Egyptian blue"-like blue, are incredibly rare.

This discovery is an example of a very basic set.

Two interpretations are possible given the numerous rooms, their layout, the abundance of ornamentation, the two sizable galleries, the hydraulic network, and the archaeological artifacts found (such as ceramics, building blocks made of copper alloy, tableware, etc.).

Given their monumentality, these artifacts might be a luxurious person's domus (residence) or a spa complex that is available to the public.

Only 100 meters (328 feet) separate the magnificent complex from the Porta de Mars, the greatest surviving Roman triumphal arch from the third century A.D.

The arch was called after a nearby Temple of Mars and was one of four formidable entrances within the city walls.

This area was extremely prestigious in the third century, but by the start of the fourth, it had all but been abandoned, and its structures had been mined for reused building materials.

The shift could have resulted from the building of Reims' walls in the fourth century.

The land was used for agricultural over the following 1400 years before it was settled at the end of the 18th century.
