It is very easy to associate the end of Bayis Sheni with the end of 
Korbanos. But I wonder if it is correct.

My knowledge in these areas is sorely lacking, but my impression is 
that the main obstacle to bringing the Korban Pesach, even nowadays, 
is not knowing the exact location of the mizbayach. And this is 
certainly something that was common knowledge for the first years 
after the churban.

Tumah was a problem for other korbanos, but not for Korban Pesach. 
(And maybe not for other korbanos or avodos either, for all I know.) 
So I am curious: Is it possible that some korbanos were brought even 
after the Churban? When was the last korban?
