There's something spooky yet appealing about seeing crypts and vaults. If this sounds interesting to you, take a look at Jehangirs Tomb.
You'll have no end of sightseeing choices when spending time in Lahore. Jehangir's Tomb is an ideal place to kick off here, but there are many other fine attractions to check out. Liberty Market, Gaddafi Stadium, and M.M. Allam Road are close to the tomb site and will fill in your day nicely.
