Obelisk at Holzmarkt

The octagonal, sloping square was designed by the Italian master builder Donato Giuseppe Frisoni. It helps to overcome the difference in height between the castle and the market square and, as the name suggests, served the timber trade for many years. Today there is a roundabout on it. The obelisk in the middle of the square was erected in 1953 on the site of a fountain. One of the four pages is dedicated to the four great Ludwigsburg poets:

Justin Kerner,
David Friedrich Strauss
Theodor Friedrich Vischer and
Edward Moerike.

Someone has to explain to me the connection between poets and the wood market

The monument on the Holzmarkt is dedicated to four famous personalities of the city: Justinus Kerner (born 1786 Ludwigsburg, died 1862 Weinsberg), Friedrich Theodor Vischer (born 1807 Ludwigsburg, died 1887 Gmunden), David Friedrich Strauss (born 1808 Ludwigsburg, died 1874 Ludwigsburg), Eduard Mörike (born 1804 Ludwigsburg, died 1875 Stuttgart).
