The Best Cathedrals

Ulm Münster, Ulm: The 161m (536-ft.) spire of this cathedral is the tallest in the world. Although its foundations were laid in 1377, this skyscraper wasn't completed vertically until 1890.

Kaiserdom (Imperial Cathedral), Speyer: Partly because of their age, Romanesque churches are the most impressive symbols of early medieval Germany. This massive church, from 1030, has four bell towers, a cornerstone laid by one of Germany's earliest kings, Konrad II, and an undeniable sense of the (anonymous) architect's aesthetic links with the traditions of ancient Rome.

Dom St. Peter, Worms: This church is a grand example of High Romanesque style, its oldest section dating from 1132. The Diet of Worms, held here in 1521, condemned the beliefs of the young Martin Luther and banished him to the far boundaries of the Holy Roman Empire.

Cologne Cathedral, Cologne: Based on French Gothic models in Paris and Amiens, this cathedral was envisioned as one of the largest religious buildings in Christendom. It required 600 years to finish -- work stopped for about 300 years (1560-1842), until the neo-Gothic fervor of the romantic age fueled its completion. In 1880, it was inaugurated with appropriate pomp and circumstance in the presence of the German kaiser. Today, its vast russet-colored bulk towers above Cologne, instantly recognizable from miles ctix.

Cathedral (Dom), Aachen: Its size and the stonework dating from 1414 are deeply impressive, but even more so is the cathedral's association with the earliest of the German emperors, Charlemagne. He was crowned in an older building on this site in A.D. 800. The cathedral's treasury contains gem-encrusted Christian artifacts from the 10th century whose heft and barbaric glitter evoke pre-Christian Germania.
