One of the largest squares in Vienna, Karlsplatz is dominated by the huge, baroque Karlskirche church, which was built between 1716 and 1737 with designs influenced by the architect's visit to Rome. The square is also well known for a pair of pavilions that were created in 1898 and 1899 by Otto Wagner and contain marble slabs and green-painted, wrought-iron frames that are decorated with gold-colored sunflowers and gilded trim.
The western side of the square contains the Secession Building, which is an art museum, and the Naschmarkt, which is Vienna's most popular market. The eastern side of the park is bordered by a park called Resselpark where you can find several statues of famous Austrians. Also near the square are several cultural institutions including the Musikverein, a concert hall that is home to the Vienna Philharmonic, and the Kunstlerhaus, an art gallery and exposition hall. The History Museum of Vienna is located on the eastern side of the square as well.
