The starting point of the Odenwald Limes has not to date been definitively determined; one possibility is the fortress at Obernburg (ORL 35), built between 100 and 110 AD,[1]: 70 but this question can only be resolved by further excavations.
Recent research suggests that the "Pfitschengraben", a deep wooded gorge that provides a direct connection between the Main and Kastell Seckmauern, may represent the beginning of this stretch of Limes.
Through ageophysical survey at the beginning of the twenty-first century it was determined that a portion of the fortifications on the south side had fallen in a heap into the moat.
Scattered evidence and inscriptions point to a possible construction in the time of Domitian, but the majority of the total scant finds date from the middle second to the early third century.
Until it reaches Seckmauern there are believed to be three unidentified sentry posts, based on topography and the distance between two identified watchtowers, but they have not been proven archaeologically.
An additional watchtower (Wp 10/4 "Bei der feuchten Mauer") is believed to be located in the immediate vicinity of Kastell Seckmauern, but has not been identified.
Kastell Wörth and the adjoining Limes construction are archaeological monuments (Bodendenkmale), according to the Bavarian Monumen Protection Law (Bayerischen Denkmalschutzgesetz (BayDSchG)).
