Kremlin and Red Square the Western walls of the Kremlin were defined by the River Neglinnaya
"The Kremlin was built on a hill west of the Neglinnaya, using the river as a moat" (Wiki) and "At one time the River Neglinnaya, a tributary of the Moskva, flowed along here protecting the Kremlin walls. There were two bridges over the Neglinnaya, a drawbridge by the Pine-Grove Tower and a stone arched bridge linking the Trinity and Kutafia towers".
Paris, Banks of the Seine The original effluence of the River Bievre into the Seine was where the Rue de Bievre is situated today - situated on the south bank at the eastern end of Ile de la Cite. It has since been moved further east. See ; link
