175 years of WIEHAG
WIEHAG celebrates 175 years
of timber construction history
WIEHAG has a long and eventful history. Since Josef Wiesner registered as a master carpenter in the guild book of the "honorable craft of carpenters" in Altheim in 1849, his successors have built the business into an internationally successful timber construction company over five generations. Under the leadership of Erich Wiesner, numerous large-scale projects and renowned architectural structures are developed and constructed today
