A massive mirror hall on the western flank of the yard is graced with remarkable interior designs and a lot of inscriptions which date back to the reign of Mozaffar ad-Din Shah Qajar.
The center, which dates back to the Qajar era, was built by Abdollah Khan also known as Biglar Beigi.
Currently, the building is a museum where different styles of handwriting and old documents owned by the Biglar Beigis are on display.
