The Bridge of Empires
Every arch has known a different empire
📱 1 to 10 phones · 1 team per phone · Independent codes
Mérida's Puente Romano has crossed the Guadiana for two thousand years. Romans, Visigoths, Arabs and Christians have all walked its arches. This game follows the thread of water and history — from empire to empire, from bank to bank.
The river that watched every empire pass
The Guadiana flows peacefully beneath the longest Roman bridge in the world. On its banks, every civilisation left its mark: the Romans built the bridge and aqueduct, the Visigoths raised basilicas, the Arabs constructed the Alcazaba with Roman stones. Mérida is a city where empires do not follow one another — they stack.
« "This bridge is the very symbol of permanence — built by one empire, it has outlasted all the rest." »— — José Álvarez Sáenz de Buruaga, archaeologist, 1950
Mérida — the city of a thousand lives
The Puente Romano was built in the 1st century BC to connect the new colony of Augusta Emerita to the Roman road leading to Olisipo (Lisbon). Nearly 800 metres long with 60 arches, it became the vital artery of Lusitania. A few kilometres away, the Aqueduct of Los Milagros — the aqueduct "of miracles" — carried water from the Proserpina reservoir on its 25-metre-high granite and brick pillars.
In the 5th century, the Visigoths made Mérida the spiritual capital of their Iberian kingdom. The city became an important episcopal centre. But in 713, the Umayyad armies took the city. Rather than destroy everything, they reused Roman ingenuity: the Alcazaba, built in 835 under Abd al-Rahman II, incorporates Roman columns, capitals and tombstones into its walls. Its central cistern is fed by a still-functioning underground Roman conduit.
The Conventual, a former fortress of the Order of Santiago built in the 13th century after the Reconquista, completes the picture. Every monument on this route is a chapter in a life-sized history book — a story of conquests, recycling and survival spanning twenty centuries.
