Goshuin number 3 is from the 大勧進 (Daikanjin), another temple in the Zenkōji complex.
Not much to say about this temple unfortunately; after getting the awesome stamp from the Daihongan, I went next door to this temple. However, there were no nice ladies to give me pamphlets in English, just tired looking monks who wordlessly took my stamp book and added it to the pile. Wikipedia says that this temple is home to an illustrated copy of the Tale of Genji which is pretty cool.
