Context

The discovery at UNESCO listed Gerulata site in Slovakia reveals advanced engineering capabilities of Roman Empire & importance of archaeological preservation in understanding past civilizations.

Key Highlights

Roman aqueduct was uncovered during restoration work at Rusovce Manor Neo-Gothic building in Bratislava Slovakia.

The manor stands on site of Gerulata Roman military camp that was part of Danubian Limes frontier defense system of Roman Empire.

This area is part of UNESCO World Heritage Site increasing importance of find.

Aqueduct Structure & Features

The aqueduct is estimated to be over 100 feet long with 38 meters of it fully documented.

It was constructed using Roman bricks (tegulae) & over 51 tons of stone.

The design includes gradual slope intended to transport water likely to a bathhouse or another facility for Roman soldiers.

Some bricks bear manufacturer stamps including one reading C VAL CONST KAR” believed to refer to Gaius Valerius Constans Roman brickmaker from Carnuntum (present day Austria).

Remarkably well preserved for nearly 2,000 years aqueduct is considered unparalleled in Slovakia in terms of integrity.

Several bricks have paw prints of animals left behind while drying in sun offering unique, humanizing glimpse into ancient construction practices.

The aqueduct may have served a bathhouse although exact destination of water remains uncertain.

Experts believe aqueduct was filled in at end of 2nd century CE which helped preserve it for two millennia.

Associated Archaeological Finds

Artifacts from Roman era found nearby include Terra sigillata (fine Roman pottery) from France & Germany, Window glass fragments as well as Personal items like a silver bracelet & an antique coin pouch.

A medieval kiln was also discovered likely used to process marble statues & reliefs from abandoned Roman camp.

An early modern icehouse structure from 19th century was uncovered used by Zichy family to store ice.

Broader Historical & Ecological Significance

The discovery is a testament to Roman engineering sophistication demonstrating advanced knowledge of hydraulics & construction.

The find contributes to understanding of human environment interaction in ancient times & infrastructure supporting Roman military life.

The aqueduct links past civilizations with modern archaeological science enriching historical narrative of European Roman frontier zones.

Preservation & Future Research

Slovak Monuments Board with government support is taking measures to preserve aqueduct in situ (in its original location).

A planned technical services building has been re-routed to avoid damaging ancient structure.

Further excavations are scheduled particularly in areas around servant house potentially revealing more about Roman & post-Roman history.
