Unlike other historical houses in Smíchov, the house in which the U Váhy inn is located has survived to the present day. The first written mention of the house is 312 years ago, and the oldest evidence of the house as an inn dates back more than 222 years. 

On the Plan of Smichov and Košíř this house is clearly drawn in 1713. According to the Josefín Land Register from the beginning of the 19th century, this house was a manor house with an attached orchard and vegetable garden. The owner at the time was Prince Jan Adolf Prince of Schwarzenberg.

According to the Stable Cadastre, this house was a residential and farm building in 1840-1857. This is evidenced by the vaults throughout the ground floor of the inn. The building was apparently a small plot of land under the administration of the Prague magistrate, it was a so-called dominical land (manorial land, which the magistrate cultivated on his own with the help of the court family and the labour of the serfs). The owner was FRANTIŠEK KOVAŘOVIC. After 1857, KAREL ŽITNÍK became the new owner and ran the building as an inn. In 1882, the owners of the house changed again, who became the husband and wife team of JOSEF AND FRANTIŠKA FRANK and they were also the innkeepers. In the meantime, the owners changed again and became the husband and wife team of JAN AND MARIE PAVLIS. At that time the inn was called "U Škrobařů". We have a preserved contemporary photograph from this period.
