The frontispiece shows a map of the small Italian town Palmanova in the 17th century. Palmanova was built up by the Venetians in 1593 as a fortress and has the shape of a nine‐pointed star. In this Concept article on page 12107 ff., different strategies and tactics for the challenging synthesis of functionalized nine‐membered carbocycles are compared and classified into the following categories: the ring‐expansion of smaller rings, the ring‐contraction of larger rings, the direct cyclization of acyclic precursors and the cycloaddition/reversion.
