This boundary stone is a three-marker, i.e. the boundaries of 3 owners (= the communities of Wachenheim, Deidesheim and Forst) meet here. The following symbols can be found on it:
Diamond pattern (top right): Coat of arms of the Electorate of the Palatinate, which belongs to Wachenheim.
Cross WITHOUT a bar at the bottom: Forst boundary sign.
Cross with a small bar at the bottom: Deidesheim boundary sign.
Pan handle (top left): This is where the stone gets its name from. The forest district is called "Pfannenstich".
Footprints mean something like: "This is where I went, this is where I stood, this is where my rights go."
The year 1488 in Roman numerals: However, you can only make out the number "1487" because the last Roman numeral (I = 1) was damaged. However, the year "1488" is still present on a border walk from 1747 (a corresponding description of the Deidesheim border from 1747 can be found in the State Library in Speyer).
The year 1789 (bottom center): stands for the year of the French Revolution; there are also two abbreviations: BMHH = Mayor Heinrich Häusling (Deidesheim Mayor); Jacob Klug = also from Deidesheim
The year 1784 (second number from bottom right) in Roman numerals
The year 1818 (bottom right) also in Roman numerals. However, you can normally only see the Roman numeral "1810" here, because the missing number sequence "VIII" (= 8) is a little lower in the bottom right corner. So if you clean the stone thoroughly at this point of leaves and sand, the complete number sequence for the year "1818" appears!
Small circle (left of the Electorate of the Palatinate coat of arms): This letter "O" is the (very old) consecutive numbering of the ground rocks. - From the 1820s, when the Palatinate became part of Bavaria, these letters were replaced by numbers. So "O" became "202" (seen here as "Z0Z"). For the sake of simplicity, a "Z" was carved into the stone instead of the "2" (also occurs in other places). - Even today, this rock is listed as "Loogfels No. 202" in the cultural monument list of the state of Rhineland-Palatinate.
