The stone bridge over the Šárka stream stands in the village of Lobzy, which has been commemorated since 1115, when it was acquired by the Kladruby monastery. On the bridge, from which two stone arches have been preserved, stands a statue of St. John of Nepomuk.
The village of Lobzy was located on an important provincial trail leading from Prague, Rokycany and Stará Plzen (today's Stary Plzenec), which continued northwards across the Mži River above Plana to cross the imaginary border between Bohemia and Germany somewhere near Cheb in the direction of Bamberg in Germany.
When the village was founded is unfortunately not documented, the first written mention of the village is from the year 1115 where it was mentioned in the chronicles of the Kladrub monastery. Vladislav I., who, in addition to Lobz, also assigned to the monastery a part of the border forest between the rivers Mže and Mžica (that is today's Úhlavka) with named villages. There is a very important sentence in that document, which literally says in Latin:
"... exceptis duodecim villis, que antiquitus fuerunt ibi constitute, scilicet: Lom, Benessewic, Lobzi, Plezomi, Malcouici, Maleulaz, Chekouici, Skuirino, Bonatici, Naztaremzedle, Dalemisle, Prostoborici.
