Weilheim has an old city-wall, historic houses and a museum. The oldest traces of human settlement date back to the Bronze Age and there were grave finds from the Late Roman era. The name Weilheim is interpreted as a home to the Roman villas. There are, however, several other theories for the roots of the name. Upper Bavaria came in Roman hands through commander Drusus. The Romans built "Via Raetia" in 200 AD, which led over the Brenner Pass to Augsburg. This Roman road ran through the Weilheim area. Around 476 AD, the Romans withdrew southwards and the Bavarians came into the region.
