The expansion of the city in the 19th century meant the end of the medieval walls and its seven entrances. However, the most beautiful of them, the Spalentor, remains. Erected in the 14th century, this gate still possesses a very impressive oak portcullis. Just inside lies a copy of the city's customs decree of 1795, a great piece of history. The gate is adorned with beautiful glass tiles and 15th-century figures. The originals can be viewed in the Museum of History.

Two slender towers characterize this red sandstone church. Climb at least one to appreciate the stunning view. Although Münster Hill was already inhabited by the time of the Celts, the present late-Roman/early-Gothic building was mostly constructed in the latter part of the 12th century. In 1356, five towers were destroyed in an earthquake. The famed humanist Erasmus of Rotterdam is buried here. The Roman gate is notable for its many old stone figures.

Ernst Beyeler is without doubt one of the world's most renowned gallery owners and collectors. Rarely do you find the work of so many masters under one roof. Beyeler, with the help of his wife Hildy, has accumulated over 180 modern classics. Important works by Cézanne, Van Gogh, Picasso, Warhol and Bacon highlight the collection. The museum shop offers a wide range of high quality books, art cards and special design objects.
