Sankt Goar is a town on the west bank of the Middle Rhine in the Rhein-Hunsrück-Kreis (district) in Rhineland-Palatinate, Germany. It belongs to the Verbandsgemeinde of Sankt Goar-Oberwesel, whose seat is in the town of Oberwesel.
Sankt Goar is well known for its central location in the Rhine Gorge, a UNESCO World Heritage Site since July 2002. Above the town stand the ruins of Burg Rheinfels, one of the castles for which the Middle Rhine is famous, and across the river lies the sister town of Sankt Goarshausen with its own castles, Katz and Maus (“Cat” and “Mouse”). The famous Lorelei rock is close-by, slightly upstream on the opposite bank.
Sankt Goar lies in the Rhine Gorge and the narrow canal on the Rhine that flows through the Rhein Massive. This part of the gorge on the left bank borders on the edge of the Rhein - Hunsrück, on the right bank it Borders on the Banks of the Taunus. The characteristic narrow-valley form came into use through downcutting in a massive that was undergoing an uplift.
Goar (born before 390, died between 446 and 450) was a leader of the Alans in 5th-century Gaul. He led his followers over the Rhine during the multi-tribe invasion of Gaul in 406, but quickly joined the Romans, and subsequently played a role in the internal politics of Gaul.
Goar is first mentioned in Gregory of Tours's description of the barbarian invasion across the Rhine on December 31, 406. A number of tribes took part in this invasion, including Goar's Alans, another party of Alans led by Respendial, the Asding Vandals led by Godigisel, the Siling Vandals, and several groups of Suevi. It is not stated where these groups originated from, though most historians identify these Alans with those settled by Gratian in Pannonia c. 380.
According to Gregory, the Roman-allied Franks attacked the Asding Vandals by Mainz while they were in the midst of crossing, killed Godigisel, and were on the verge of exterminating the tribe. But at that point the other Alan king, Respendial, came to the Vandals' rescue and defeated the Franks, "although Goar had gone over to the Romans." It's unclear from Gregory's account whether Goar actually joined the Franks in fighting his co-invaders; but in any case, he remained in Gaul while the Vandals, Sueves, and Respendial's Alans continued into Spain.
