The palisade castle of Egerszeg is now in the city of Zalaegerszeg and it was destroyed / built-in.
The city is located in the southern part of Hungary. It was first mentioned in 1247 but the city had been founded a lot earlier. Its landlord was the Bishop of Veszprém and he had the town fortified in the Turkish times.
The Ottomans destroyed Nagykaporlak in 1566 so Egerszeg became a judicial center of the Kingdom of Hungary.
When Kanizsa fell in 1600, Egerszeg became the most important fort defending Zala county at the River Zala as it opposed the castle of Kanizsa directly. The fort had more than 300 men guarding it in 1638.
The Ottomans besieged it in 1649 but due to the brilliant information-system, the reinforcement arrived soon and the 500 Hussars of Captain Francsics István beat the enemy back.
Unfortunately, the agricultural city of the fort accepted the Ottoman rule and paid taxes to them; the fort was taken for a short time in 1664, too. It was liberated in 1690 and King Leopold I left the fort neglected in 1702.
Now, you can see only the traces of the castle in the modern city.
