Every year, the local Aktionsring Braunfels e.V. organizes the Mittelalterliches Spektakulum, which over several days attracts tourists, and showmen, for which occasion, the spa gardens are turned into a knightly encampment.

Braunfels Castle, a stately home that had been built from a castle built in the 13th century by the Counts of Nassau, served as of about 1260 as the Solms-Braunfels noble family's residential castle. After Solms Castle had been destroyed by the Rhenish League of Towns in 1384, Braunfels Castle became the seat of the Counts of Solms. Over the castle's more than 750-year-long history, building work was done many times. Particularly worthy of mention is the town and castle fire of 1679, which burnt much of Braunfels and its stately seat down. Both were then built into a Baroque residence. Braunfels Castle was rebuilt out of materials that were still on hand. The town was given a regular marketplace, which is still preserved today and lies before the town wall.

The last makeover, which defines the Schloss as it is seen today, took place starting in 1880, and was undertaken according to neo-Gothic plans by builder Edwin Oppler. Art works in the Schloss include works by the Dutch Masters, among them van Eyck, works by the Hessian Tischbein family of painters, the Altenberg Altar, parts of which are found in the Städel in Frankfurt and the Bavarian National Museum in Munich, and Saint Elizabeth's legendary ring. Sites in the castle include the courtyard, the knights' hall, the guest rooms and painting gallery, the sacral exhibition pieces from the Altenberg Monastery, the hunting paintings by Johannes Deiker, and the cannon square. Other things to visit are the Princely Family Museum and the castle church with displays about the church's building history.[citation needed]

The inner Old Town has distinctive defensive features. There is a Baroque expansion with a marketplace and great spa gardens.
