Stolberg Castle (Schloss Stolberg).
The castle stands on a hill that drops steeply on 3 sides.
The oldest part of the castle, its round tower, dates to around 1200, although its most recent elements were built in the Renaissance style between 1539 and 1547.
In the southeast wing is the Classicist Great Reception Room (Große Empfangszimmer), the Red Hall (Roter Saal), designed by Karl Friedrich Schinkel.
The castle owes its present appearance to remodelling work carried out between 1690 and 1700.
Until they were dispossessed in 1945 the castle was owned by the family of the Prince of Stolberg-Stolberg.
At present it is being comprehensively restored and renovated by the German Foundation for Monument Conservation.

Town Hall (Rathaus).
The town hall from 1454 is an architectural curiosity because it has no internal stairs.
The only access to the upper storeys is by an external flight of steps that also leads up to St. Martin's Church.

St. Martin's Church.
A Late Gothic church where Martin Luther preached on 21 April 1525 against the Peasants' Revolt.
The restoration of the three-aisled basilica from the 13th century is very expensive, thanks to its hillside location.
Here, too, the German Foundation for Monument Conservation is involved, alongside other donors.
Northwest of the church is St. Mary's Chapel.
The Müntzer Monument, made by the sculptor, Messerschmidt, was erected just in front of the town hall on the birthday of Thomas Müntzer in 1989.

Saiger Tower.
Opposite the town hall is the Saiger Tower.
It dates from the 13th century, but the upper part was replaced in the early 19th century.
It takes its name from the Saiger Smelting Works (Saigerschmelzhütte) that stood next to the tower in the Middle Ages.

Niedergasse.
The street known as Niedergasse is home to several historic buildings.
The Thomas Müntzer House (Thomas-Müntzer-Haus) is the birthplace of Thomas Müntzer and dates to 1851, but was partly burnt down.
Also on the street are St George's Chapel and the Old Mint (Alte Münze) which houses the local history museum.

Rittertor.
At the western end of Rittergasse is the Rittertor or Knight's Gate, the only surviving medieval town gate in Stolberg.
West of the gate is the Chalet Waldfrieden, built in 1810 by Karl Friedrich Schinkel and, nearby, is the spot where the Chapel of the Holy Cross stood until 1818.

Luther Beech.
On a hillside overlooking the town to the southwest is the Luther Beech (Lutherbuche) that commemorates Martin Luther.

Stag Monument.
The Stag Monument (Hirschdenkmal) is located in a wood northwest of the town.

Großer Auerberg (579 m).
The hill known as the Großer Auerberg rises not far from Stolberg.
At its summit is the 38-metre-high observation tower known as Joseph's Cross.
It is the largest iron double cross in the world.
