Bridge constructed in 1788.
The Karl Theodor Bridge, commonly known as the Old Bridge, is an arch bridge in Heidelberg that crosses the Neckar river. It connects the Old City with the eastern part of the Neuenheim district of the city on the opposite bank. The current bridge, made of Neckar sandstone and the ninth built on the site, was constructed in 1788 by Elector Charles Theodore, and is one of the best-known landmarks and tourist destinations in Heidelberg.

The Heiliggeistkirche (Church of the Holy Spirit) is only one of many large and small churches, but definitely the one with the most interesting history. During the Dark Ages, it was the shelter of the Bibliotheca Palatina, Germany's oldest library. The Bibliotheca was stolen and brought to Rome but eventually returned in pieces. Today, parts of it can be visited in the University Library (also the oldest and probably the most valuable of its kind in Germany), which is situated close to the old university. You can get a great view of the Heiliggeistkirche, Old Town, and the Neckar river bridge from the castle (Schloss Heidelberg).
Hauptstraße is the main street, which leads from Bismarckplatz across the old town. Approximately 1.6 km in length, it is reputedly the longest pedestrian shopping street in Germany.
The old armoury is now a student cafeteria (open to the public and offering good food and drinks at reasonable prices).
It has 1712 Baroque construction with modern touches inside.
The university has its own museum, in the main building of the old campus. Visitors are able to view the Great Hall (when not in use), and the former "student jail".
