SSA Veer ji
Yes there r lots of stuff there worth to be seen.
First of all, near the main Gurudwara sahib there is a dera of a Baba(sorry i forgot the name) But this is the dera where all the pilgrims stay.
In this dera's langar hall, THERE IS A REAL BLACK & WHITE PIC OF MAHARAJA RANJIT SINGH, AKALI PHULLA SINGH with the then Governor- General of India. Its a great piece of work.
Secondly, in the vicinity of main Gurudwara sahib there is this one small Gurudwara sahib built on the name of two of the 5 panj pyaras.
There is this SHRI GURU GRANTH SAHIB JI written by one of the 5 panj pyaras. If U'll ask the Granthi sahib then he'll show u that at the last panna of SGGS ji the panj pyara has made the picture of Shri Guru Gobind Singh ji.
When I had visited that place i was a kid, so didn't knew the importance of these kind of stuff. But next time I'll visit Hajur sahib, I'll take my camera and will take pictures of all the Imp stuff there.
Good Luck paaji and Plz do visit these places and if possible try to post their pics here.
WAHEGURU JI KA KHALSA !
WAHEGURU JI MKI FATEH !
