The Augarten is the oldest baroque garden layout left in Vienna, and one of its avenues runs straight into a concrete anti-aircraft tower. The court gardener Jean Trehet drew the avenues after 1708, and you walk his pattern today: straight lines of chestnut and lime meeting at two junctions, the Great Star and the Little Star. Late in the war the German air force poured two anti-aircraft towers into the middle of the garden. One of them is over fifty metres high and stands in the line of the main chestnut avenue.
Nobody has removed them. Explosives beside the flats that ring the park were judged too dangerous, and both towers became protected monuments in 2000. The rest of the park is in daily use, with school sports grounds, rented vegetable beds along the outer wall, and porcelain still made in the garden's palace. Over the gate is the sentence Joseph II had carved in 1775, the year he opened this imperial garden to everyone: a place of amusement dedicated to all people, from their admirer.
