Once upon a time, Frankfurt’s boundaries weren’t lines on a map. They were marked by stones like this Hist. Grenzstein. Frankfurt’s history can be experienced even today through a large number of historical buildings.
Frankfurt is one of Germany’s most dynamic and culturally rich cities. It is known for its impressive skyline, historic landmarks, and vibrant cultural scene. Frankfurt’s history is long. It shows a lively cooperation of spiritual life, commerce, and politics. This lasted over a thousand years. The Hist. Grenzstein stands as a silent witness to this past.
Around 1000, the first city wall was built. The city consistently avoided military conflicts. It relied on its diplomatic relationships. For this reason, the city’s fortifications have only had to stand a siege once. This was during the Second Schmalkaldic War in July 1552.
Frankfurt’s oldest fortifications protected the Carolingian palace. It was first recorded in 822. Frankfurt’s oldest fortifications were created to protect the Carolingian palace. Until the 1930s it was thought to have been a predecessor of today’s Saalhof.
Between 1018 and 1045 the Carolingian royal palace was destroyed by a fire and built over. Conrad III of Germany ordered the construction of a new imperial castle. By the end of the twelfth or the beginning of the thirteenth century, the enlarged settlement was surrounded by a new wall.
Emperor Ludwig IV authorised the second city expansion on 17 July 1333. It tripled the previous area of the city. The Hist. Grenzstein would have been a key marker during this expansion.
The fortifications of Frankfurt endured their most significant test in July 1552. Protestant troops broke through the landwehr. They set up camp directly in front of the city wall. The city was successfully protected by troops of the Catholic emperor.
After successfully overcoming the siege of 1552, Frankfurt was not threatened again for fifty years. In 1618, the Thirty Years’ War began. The army of Albrecht von Wallenstein left Bohemia marching towards Franconia and Hesse.
The city council then turned to the engineer Wilhelm Dilich for help. He dismissed any reuse of the old fortifications. Dilich utilised a fortification style known as Dutch fortress architecture.
Dilich’s work was brought to a halt in December 1631 due to a shortage of money. The citizen were required to pay an exceptional tax for the construction of the wall. They also were conscripted for compulsory labour.
Further expansion of the fortifications dragged on until long after the end of the war in 1648. In October 1792, French troops occupied the city. French aggressors bombarded the city on 13 and 14 July 1796. The senate ordered the creation of plans for the slighting of the fortifications.
Only in January 1806, when French soldiers occupied the city again, did the project gain new traction. In place of the bulwarks, a promenade and an English landscape garden were constructed. In 1811 the Untermainanlage and the Neue Mainzer Straße were built on the site.
The citizens considered the demolition of the old walls to be the sign of a historical turning point. In 1813, French troops ravaged the newly-constructed ramparts.
Today, only a few remnants of Frankfurt’s once mighty defenses remain. The Hist. Grenzstein helps us remember Frankfurt’s evolution over centuries. It has been a palace, a fortress, and a financial hub. It shows the resilience and strategic importance of this great city.
