The Faculty of Chemistry and Earth Sciences is one of twelve faculties at the University of Heidelberg. It comprises the Institute of Inorganic Chemistry, Institute of Organic Chemistry, Institute of Physical Chemistry, Institute of Geography, Institute of Geology and Paleontology, Institute of Mineralogy, and the Institute of Environmental Geochemistry. Chemistry was established as a separate discipline at the University of Heidelberg in 1817 with Leopold Gmelin being appointed ordinary professor of chemistry and medicine. 1895 is considered to be the date of foundation of Geography at the University of Heidelberg as it was from this year on that lectures in physical and mathematical geography were held on a regular basis. In 1899 the first professorship in geography was established, filled by Alfred Hettner.

Meder House (German: Haus Meder) is a protected baroque building on the Hauptstrasse in Heidelberg's old town, the Altstadt. It is a residential building that was built in the first half of the 18th century and was in the possession of the Meder family, who worked as merchants, from 1839 at the latest. The three-story house with an attic apartment is located in the eastern half of the Hauptstrasse, the main street of the Heidelberg Altstadt, on the corner with Kettengasse ("chain alley"). The showy facade on the Hauptstrasse has three windows on each floor, while the facade on Kettengasse is longer, with eight windows, but also simpler. At the corner, on the first floor is a Madonna, which was probably made by the sculptor Peter van den Branden, who also made the Kornmarkt-Madonna. The statue on the building today is a copy; the original is kept in the Kurpfälzisches Museum. The central relief on the facade, depicting the Trinity, is remarkable for their period. It is flanked by two inscriptions: "Alle Stund und Zeit sei gelobt die heilige Dreifaltigkeit" (Every hour and moment, let the Holy Trinity be praised!) and "Wer Gott verdraut hatt wohl Gebaut" (He who trusts God, has built well). The decoration of the building thus showcases the Catholic piety of its owners, during the Counterreformation in Heidelberg.

The President Friedrich Ebert Memorial (Reichspräsident-Friedrich-Ebert-Gedenkstätte) in Heidelberg commemorates the life and work of Friedrich Ebert, who was born in the house on 4 February 1871. From humble origins, he became a member of the Social Democratic Party of Germany and was finally elected as the first German democratic head of state in 1919. Faced with extreme internal and external pressures, he prepared the way for parliamentary democracy in Germany after the end of World War I. In these years he preserved national unity and made a vital contribution to the creation of a social and democratic republic.

The Church of the Holy Spirit (German: Heiliggeistkirche) is the largest church in Heidelberg, Germany. The church, located in the marketplace in the old town center, was constructed between 1398 and 1515 in the Romanesque and Gothic styles. It receives 1–3 million guests annually, making it among the most visited churches in Germany.The church was planned as the burial place of the Electors of the Palatinate and as a representative church of the Palatinate royal seat. In the Palatine War of Succession, the princely graves of the Electors were destroyed; today only the grave of the founder of the church, Elector Ruprecht III, remains. The church was also the location of the founding of the Heidelberg University and was the original repository of the Bibliotheca Palatina. The congregation was originally Roman Catholic, but the church has changed denominations more than ten times through its history. Intermittently, over a 300 year period, the nave and the choir of the church were separated by a wall, allowing both Catholics and Protestants to practice in the church at the same time. The wall was ultimately removed in 1936, and the congregation is now solely Protestant. Today, it is a parish church within the Evangelical Church of Heidelberg and is part of the Evangelical Church in Germany.

The Kurpfälzisches Museum (Palatinate Museum) is a museum of art and archaeology in Heidelberg, Germany. It is located in the Palais Morass. It was founded in the late 1870s, when the city of Heidelberg purchased the private collection of the artist and art historian Charles de Graimberg.
