The list stays with the words a tourist hears on the floor — not a church-office dictionary of dioceses and order abbreviations.
- Ambo
- The raised reading desk in the crossing. Guides sometimes call it a pulpit. It is where Scripture is read, not a visitor viewpoint.
- Apsis / apse
- The rounded east end of the church, behind the high altar. In Cologne the gothic choir wraps around this end, so you walk the ambulatory instead of standing in a simple half-circle.
- Basilica
- An architectural word: a long hall with a higher middle aisle that has its own windows. Cologne Cathedral is a five-aisle gothic basilica. It is also, separately, a papal honorific title. Visitors usually just mean the tall middle space.
- Choir / inner choir
- The east end reserved for clergy seating and the high altar. Stone screens keep the tourist path in the surrounding aisle. The 14th-century choir-screen paintings are among the best medieval pictures still in the building.
- Choir stalls
- The carved wooden seats facing each other across the inner choir. Look under the folding seats for misericords — small shelves that let someone half-sit during a long standing liturgy. Many are carved with animals and jokes.
- Clerestory
- The top window zone of the nave walls. Those high lights are why the middle aisle feels brighter than the side aisles.
- Crossing
- Where the long nave meets the transept. Stand here and you can see all four arms of the church. The crossing tower above you is the shorter central spire, not the twin west towers.
- Dicker Pitter / Petersglocke
- Cologne’s famous south-tower bell, recast in 1923 after the medieval predecessor cracked. Locals still call it Dicker Pitter. You hear it from the city; you do not stand next to it on the public tower climb, which ends at the 97 m platform.
- Dombauhütte
- The cathedral works yard — masons, glaziers and archaeologists who keep the stone from dissolving. The word also means the institution itself.
- Domkapitel
- The cathedral chapter: the clergy body that administers the building. This website is a visitor guide and is not the chapter.
- Finial / Kreuzblume
- The leafy stone flower on top of a pinnacle. Official counts put more than a thousand large pinnacles on the exterior. They are decoration and rain-shedding, not lookout posts.
- Flying buttress
- The open stone arches that lean against the upper walls and carry vault thrust down to outer piers. Without them the high windows would have pushed the nave apart. Best seen from the south side and from the tower platform.
- Gero Crucifix
- The large oak crucifix given by Archbishop Gero around 970. It hangs in the chapel named for it, north of the choir. It is older than the gothic cathedral. Details: Gero Crucifix guide.
- High Gothic
- The mature gothic style of the 13th century — pointed arches, rib vaults, huge windows. Cologne’s choir, begun in 1248, is a German high-gothic answer to Amiens and Beauvais. See the architecture page.
- Nave
- The long western hall where most visitors walk first. In Cologne it has a tall middle aisle and two lower aisles on each side. The floor mosaics under your feet are 19th-century, not medieval.
- Pinnacle / Fiale
- A skinny stone turret sitting on a buttress. Weight at the top helps the flying arch do its job. Do not confuse them with the two west towers.
- Richter Window
- Gerhard Richter’s 2007 south-transept window: 11,263 hand-blown glass squares in a computer-shuffled grid. It replaced 19th-century glass lost in the war. More on the stained-glass page.
- Roncalliplatz
- The square on the south side of the cathedral. The central ticket office is at Roncalliplatz 2. The Christmas market stalls sit here in winter. The plaza itself is free; interior tourist entry is not.
- Shrine of the Three Kings
- The large gilded reliquary behind the high altar, made after the relics arrived from Milan in 1164. It is why medieval pilgrims came and why the gothic church is so huge. Visitor notes: Shrine guide.
- Tracery / Maßwerk
- The stone lace inside a gothic window. Early Cologne windows use simple circles and pointed lights; later ones get denser. It holds the glass and is part of the structure, not applied decoration.
- Transept
- The north–south arms that give the plan its cross shape. The south transept faces Roncalliplatz; the north side is quieter and has the step-free entrance.
- Treasury / Schatzkammer
- The museum next to the cathedral, not the shrine inside the choir. It holds liturgical gold, the Frankish grave finds and processional pieces. Separate ticket. See Treasury tickets and highlights.
- Triforium
- The arcaded gallery between the side-aisle roofs and the clerestory. In Cologne it is a dark middle band on the nave walls. You cannot walk it as a visitor.
- Triforium (outer)
- On the exterior, a walkable gallery around the choir at about 27 m. Not part of the public tower ticket.
- Vault / rib vault
- The stone ceiling. Diagonal ribs meet at a boss. The nave vaults sit more than 43 m above the floor — that height is the point of the whole gothic system.
- West façade
- The twin-tower front facing the Hauptbahnhof. Designed in the Middle Ages, finished in the 19th century from the surviving parchment plan. The south tower is the one you climb.
