Halakhah su Deuteronomio 16:5

To not sacrifice the Pesach sacrifice on the bamah (altar) of an individual: That we were prevented from sacrificing the Pesach lamb on the bamah of an individual, and even during the time that [a bamah was] permissible. And the matter of the bamah is that before the building of the Choice House, each and every individual from Israel who wanted to offer a sacrifice would build an edifice in any place he wanted and offer his sacrifices there to God, may He be blessed. And even at that time when it was permitted for them to do so, [that was] specifically with the other sacrifices. But we always only offer the Pesach sacrifice on the community altar, and that is the place where there was the tabernacle there. And about this is it stated (Deuteronomy 16:5), "You may not slaughter the Pesach in one of your gates." And likewise they, may their memory be blessed, said at the end of the first chapter of Megillah 9b, "There is no difference between a large (communal) bamah and a small (private) bamah besides Pesach sacrifices."
