Linköpings Trädgårdsförening is the city's garden society park, a landscaped green space close to the centre with lawns, mature trees, flower beds, and glasshouse planting. It is not a wilderness escape; it is the sort of civilised Swedish town park that makes a city easier to enjoy on foot.
Use it as a quiet break between the cathedral, old streets, and museums. In warm weather it is a good picnic stop, while the planting and greenhouse give it more character than an ordinary patch of grass.
