In the 14th century, a wooden fortress stood in these places, which was in such a bad condition around 1363 that the then owner of Poříčí had a new fortress built in Ledce, and thus acquired the surname of Ledce. On the site of today's courtyard there was an ash yard with a proper ratejna, where there was an apartment of the manager, a kitchen and a large room for accommodation of the workers working in the ash yard. When Poříčí became an independent manor again in 1525, it belonged to Karlík the Younger of Nežetice. However, he stayed mainly in Prague, where he inherited the house from his mother. After his death in 1542, Poříčí was inherited by his sister Eliška of Nežetice, whose third husband was Jan Opita of Maličín, the king's chief resmister. This is probably why they also resided in Prague. His son Jan Opita of Maličín, who was born in 1549, had a new fortress built in Poříčí. However, he was forced to sell the Poříč estate after he went into debt.
The stronghold was the seat of the village's authorities. At the beginning of the 17th century, the outhouse was converted into a tavern. From then on, until 1810, the lord of the manor rented out the inn with the innkeeper also collecting tolls from the bridge. He handed over a predetermined amount, the rest was left to him. This caused great interest in this inn, which was named "Na Mýtě". The inn later belonged to the Pank family, who were the parents of the children's tutor Countess Kounicová, a benefactress of the writer Božena Němcová. She lived in great poverty in 1856 and had to move to Poříčí with her children. At the end of July of that year she was really going to move there, but on the 29th Karel Havlíček Borovský died and Němcová's husband was condemned for attending the funeral. Němcová stayed with him in Prague at this time and sent only her children to Poříčí for eight weeks. She herself never made it there again.
In 1894, the inn and its yard were bought by Archduke Ferdinand d'Este, who in 1904 exchanged it with the Marks for their farm in Žabovřesky. This building is now known as 'Marko's Court' and is part of the stables.
