The western and northern parts of the historic center of Jelgava forms a landscape in which there is preserved evidence of cultural and historical objects representing different centuries. The identification, restoration and preservation make it possible for the town to recover identity of its landscape space. The research includes analysis of the former Duke Jacob’s canal with the prewar and current structure of the buildings and the green planting zones, partially restoring the historical bed of the watercourse. The rows of trees along the canal, the green slopes of the banks and the pedestrian bridges until the 30s of the 20th century brought in the town’s dense building an aesthetically high-quality green space for recreation.
