🏛️ Bath: Roman Spa City Turned Georgian Showpiece

A 3D cutaway simulation of the Roman Baths' hot-spring hydrology and hypocaust heating system, with a control to excavate down through the Georgian city built above.

A 3D cutaway of the Roman Baths at Aquae Sulis, showing the hot spring rising through a geological fault to fill the Great Bath and feed a hypocaust hot-air heating system — buried six metres beneath the Georgian city that was later built directly on top of it.

🔬 What It Demonstrates

Geothermal water rises along a fissure into the Great Bath while a furnace-driven hypocaust pushes hot air under a raised floor and up through wall flues to heat the caldarium — the two heat sources that made the Roman spa function.

🎮 How to Use

Drag the "Excavate through time" slider to lift the Georgian street, Pump Room and terraces away and reveal the Roman ruins below, then adjust the spring flow rate and hypocaust fire to see the heating systems respond.

💡 Did You Know?

The Roman baths were lost for centuries under silt and Georgian foundations, only rediscovered by Victorian engineers investigating a leak in the 1870s — the same layered history this simulation lets you dig through.
