The Vindelici tribe constructed the settlement known as Manching close to the Danube River. This walled city, enclosed within some 380 hectares, comprised carefully laid out streets and impressive outer walls. These were constructed box-like structure of criss-cross timbers placed horizontally, with stone walls then built on either side of the timbers. The centre was filled with rubble and stones, creating very thick, strong walls. When Caesar came across this particular construction technique he called it 'Murus Gallici', or 'Gallic Walls'.
