The tabernacle “historically” resided at the back of the main altar. For several decades now, they are often found off to the side, or in a small chapel. Several priests I have talked to have explained that the “off to the side” or in a chapel is actually proper.
Not according to the new GIRM of 2002 (approved by the NCCB) or the Pope’s document, Redemptionis Sacramentum. Both documents insist that the Tabernacle should be on an altar in conspicuous view–they do not say the placement should be either way–that the Tabernacle should be set off to the side in a room by itself or not. The documents mention that if the Tabernacle is put in a chapel by itself (and not on the main high altar), the chapel should be suitably decorated and conducive to prayer.
The only real reason this should be done is when the main church building is very busy during most days and because of the constant funerals, weddings, visitors, etc. the local faithful could not spend any prayer time with the belssed Sacrament.
What you say is contradictory. You first say that there is no mention of it being allowed for the tabernacle to be at the side or in a separate chapel but then you go on to say that **if its in a separate chapel it should be suitably decorated and conducive to prayer. **
Read my post again. I said that the documents don’t say that the Tabernacle has to be in a separate room or on the high altar–just that the placement needs to be “conspicuous”.
And how does my post actually differ from yours?
My post was not contradictory (as was accused). I simply said what was decreed in the current documents–documents that anyone can check for themselves.
You should re-read your post and mine.
The documents mention “an” altar–not the high altar nor the one used in the Mass–and it does need to be conspicuous. (Now IMO that is plain common sense considering the importance of Eucharist/Jesus for Catholics. I, myself, have had a visitor to a parish that doesn’t have the Tabernacle in a conspicuous place ask me “Where’s the Tabernacle? Am I in a Catholic) Church?”)
There was also an outside entrance. The new altar was on what was the side of the church and the old entrance was just an empty area over to the right. A whole new entrance had been created on the other wall with a big foyer for “fellowship” I guess. 
In the church we regularly attended while living in that area for a year or so, there was a tabernacle behind the altar but separated by a wooden screen like effect with a gauzy curtain. Not bad, really because the whole church was so beautiful. You could see the tabernacle behind the screen and there was a red light up above. They also had an Adoration chapel to the left of the front of the church which was lovely and I enjoyed going there. Since then they have built a totally separate one with a big tall ugly, IMHO, bell tower. I hope they haven’t removed the tabernacle from the altar area but I doubt we will be going back there. Anyway, is there some rule that says that the tabernacle can be in the church…conspicuous as ours is in our new church…yet also in an Adoration chapel? I’ve wondered about it since it has happened several times that the Blessed Sacrament has had to be moved to the cry room if there’s funeral on the all day Adoration times. Our Pastor does not want a Chapel but still…why not both? 
( 
to Jean) M.A.There is only supposed to be 1 tabernacle in a Church.I too have gone in to a church in which I could not find the tabernacle, at all. I found that the beautiful church had been remodeled in a most horrendous way in which the old altar area is now the Adoration room, with a wall that was decorated with what looked like a connected screen with donation plaques on it, and was just to the left of where we were sitting,and I hadn’t realized it, with an entrance I couldn’t find until Mass was over. It was NOT conspicuous.
Why would they repose the Blessed Sacrament in two different places in one building?
So an Adoration Chapel is perfectly fine as long as there is no search required to locate it within the church.
(all emphasis mine)
no it is perfectly acceptable, and may be preferable if there are reasons proper reverence for the sacrament may be at times lacking in the body of the church, such as a historic church or pilgrimage site visited by tourists
Sounds like the new church being built in the next parish. The tabernacle will actually be in the chapel, but a glass door at the back of the main altar will be opened during Mass in the main church. Said glass door will make the tabernacle viewable from either side.
I never did open the door to that room and see how it was arranged. The church itself does not have a Tabernacle that I could see. This church had a beautiful entrance foyer but then you entered the church by turning to the right, not straight on, and it seemed more like a theater with a floor that slanted down to the raised altar area…quite modern yet had beautiful statues and Stations OTC. There was a choir pit to the left of the altar with microphones that hung down on tiny wires. There is another older traditional church we visited in which there is a tiny Adoration chapel with the tabernacle there (The Host not exposed in a monstrance) to the left of the altar area. The door to this chapel is open and there is a red light outside the door and it is readily available for more Blessed Hosts if needed during Mass.There seems to be as many ways of doing it as there are Parishes. The 2002 GIRM indicates some requirements for the Tabernacle and that if there is a separate Adoration Chapel for the Tabernacle:
Never heard of a Ressurection Room.
