A little outside the city lay the ‚Rheinische Hof‘. It offered travelers who couldn’t get into the city in time before the city gates closed accommodation and food. From 1718 to 1854, the inn was Thurn and Taxis's Post Office Accommodations were provided here. The post-carriages station was located here; before the construction of the railway, these were the most important means of transporting passengers. Numerous guests stopped in St. Goar during their journey along the Rhine between Mainz and Koblenz at this time.
As the Prince of Thurn and Taxis and the Hessian Landgrave disputed the postal rights, in the 18th century there was a time when the Imperial Thurn and Taxis Post Office and the Hessian Landgrave Post Office existed simultaneously in St. Goar. The competition was so great that the Thurn and Taxis postal officers were temporarily forbidden from entering the fortress area of Rheinfels. Only the French occupation ended the co-existence of the two postal services in 1797. In 1816 postal rights in the city were transferred to the Royal Prussian Post.
Shortly after the railway line was inaugurated, in 1859, the unprofitable horse-drawn carriage service on the Rhine line was discontinued. The ‚Rheinische Hof‘ was demolished after the departure of the postal service; in its place, the Guesthouse ‚Zur guten Quelle’‘ built. Today the Rheinfelshalle.
