Lower Middle Rhine Region
The lower Middle Rhine area is a natural spatial main unit within the main unit group Middle Rhine area on the Middle Rhine . It extends from the Rhine Valley immediately below Andernach to immediately above Bonn and also contains hilly landscapes on both sides of the Rhine and the Siebengebirge .
Most of the Lower Middle Rhine region lies in Rhineland-Palatinate , its north in North Rhine-Westphalia , and separates the Westerwald in the east from the Eastern Eifel and Voreifel in the west. To the north it goes over into the Lower Rhine (Cologne) Bay .

Lower Middle Rhine Valley
The Lower Middle Rhine Valley is the valley landscape of the Middle Rhine from immediately below Andernach to immediately above Bonn . It is divided in the direction of the Rhine into the Andernacher Pforte, the Linz-Hönninger valley widening and the Honnef valley widening. Due to its extensive valley widening, among other things, the geographers Heinrich Müller-Miny and Martin Bürgener defined this section of the valley, including the flanking main terraces (Rhine-Ahr terraces and Linz terrace), as the Middle Rhine Bay , and Müller-Miny, including the Pleiser Hügelland and the Siebengebirge, as the Middle Rhine Mountain bay . Müller-Miny and Emil Meynen proposed to combine the mountain bay with the Lower Rhine (Cologne) Bay to form a Rhenish bay , whereby their different large-regional allocation to the Rhenish Slate Mountains on the one hand and to the North German lowlands on the other would remain unaffected.
Andernach gate
The Andernacher Pforte , located on the left bank of the Rhine in the district of Mayen-Koblenz and on the right bank of the Rhine in the district of Neuwied (both Rhineland-Palatinate ), is the breakthrough valley of the Rhine through the edges of the Neuwied Basin to the Lower Middle Rhine Valley formed by quartzite and slate . It covers the just 5 km long and at the beginning just 1 km, inside always under 4 km wide section of the Rhine from immediately below Andernachs to Niederhammerstein .
To the west, the gate borders on the Laacher Kuppenland , which is continued further west by the Ettringer volcanic peaks and initiates the transition into the Hocheifel ; to the east, a part of the Niederwesterwald borders directly on the southern Rhein-Wied ridge .
Linz-Hönninger valley widening
The Linz-Hönninger valley widening represents the Rhine valley above Brohl-Lützings via Bad Hönningen , Bad Breisig , Sinzig , Linz and Remagen to Unkel . It is located on the left bank of the Rhine in the district of Ahrweiler and on the right bank of the Rhine in the district of Neuwied (both Rhineland-Palatinate ) and is around 22 km long with a width of 1.5 to 3.5 km; towards the end, in the north of Unkel, it narrows to about 800 m. On the left bank of the Rhine, the valley widening includes the fertile plain of the Golden Mile .
On the left bank of the Rhine are the Rhine-Ahr Terraces, which are divided by the Ahr estuary valley of the Ahr that flows above Sinzig and widen noticeably below that on the northeastern East Eifel, which flattens out towards the Lower Rhine Bay .
On the right bank of the Rhine, in the south, the valley meets the northern Rhine-Wied ridge as part of the Niederwesterwald , while from Hönningen the Linz terraces push themselves in front of the Rheinwesterwälder volcanic ridge (also Niederwesterwald).
Honnef valley widening
The Honnef valley widening , also called Honnef Bay , is the approximately 5 km long northernmost section of the Middle Rhine from the north of Unkels via Rheinbreitbach to Bad Honnef (on the right bank of the Rhine) or from Oberwinter over Rolandseck to Rolandswerth (on the right bank of the Rhine), above Bonn (district of Bad Godesberg ) . It is characterized on the left bank of the Rhine by a steep bank up to over 100 m high, opposite to which on the right bank of the Rhine is a much wider, crescent-shaped valley area. On the left bank of the Rhine, the widening of the valley lies almost entirely in the urban area of Remagen in the Ahrweiler district (Rhineland-Palatinate) and only touches the urban area of Bonn ( North Rhine-Westphalia ) in the far north . On the right bank of the Rhine lies the south in the Neuwied district (RP) and the north in the Bad Honnef urban area in the Rhein-Sieg district ( North Rhine- Westphalia). From the narrow point in the north of Unkel, where the Rhine Valley is around 800 m wide, it widens to around 2 km, and then narrows again to just under 1.5 km. The widening of the valley contains the Nonnenwerther current splitting of the Rhine, which splits into three (formerly probably four) arms and is 874 m wide at river kilometer 641.0. On the western arm of the Rhine Roland Werther is the island Nonnenwerth , on the eastern Bad Honnef Altarm the island Grafenwerth .
On the left bank of the Rhine, the valley is accompanied by the Rhine-Ahr Terraces , which flatten towards the north towards the entrance to the Cologne Bay , the Godesberg Rhine Valley funnel, and gradually recede from it.
On the right bank of the Rhine, the Linzer Terraces connect to the south , to the east of it the northwestern edge of the Rheinwesterwälder volcanic ridge ( Niederwesterwald ), occasionally referred to as the Honnef Terrace Hill . To the east, the widening of the Honnef valley borders almost seamlessly on the Siebengebirge , which is part of the Lower Middle Rhine region.
