Though it was a small temple (compared to, say, Thiruvidanthai), it was an interesting one. I think it must be about 700-800 years old. Definitely built after Ramanujar's period, it wore a deserted look on that particularly hot day.
Sri Perumbudur is the birth place of Ramanujar and there is a sannidhi near Perumal himself for him.
All pillars had the riding horseman in it. Oddly, half of them looked Caucasian for whatever reason.
