Which capital city of a small German principality is known for being remodeled with gardens as major elements?

The capital city of the small German principality that is renowned for its remodeling with gardens as major elements is Karlsruhe. Founded in the late 18th century, Karlsruhe was designed with an emphasis on its radial layout reminiscent of a baroque garden city, featuring extensive garden spaces and parks that contribute to its aesthetic and planning principles. The city’s layout radiates outward from the central palace, with tree-lined avenues and public parks that are integral to its character. This design reflects the principles of landscape architecture that were popular at the time, focusing on harmony with nature and the incorporation of green spaces into urban settings.

In contrast, while Heidelberg is known for its historic university and romantic scenery, it does not specifically emphasize gardens in its planning. Berlin, as the capital of Germany, has a varied architectural identity and diverse landscapes but is not defined by a primary focus on gardens. Munich has beautiful parks and gardens, like the English Garden, but it is more recognized for its cultural and historical significance rather than being a small principality remodeled primarily around gardens. Thus, Karlsruhe stands out as the correct choice for its distinct garden-centric urban design.
