The Temple of Gozer is Gozer's precious shrine and its own interdimensional portal into other dimensions and worlds.
Primary Canon History
The Temple of Gozer consisted of a large ancient pyramid, a staircase, translucent doors, two altars for the Terror Dogs (Zuul the Gatekeeper and Vinz Clortho the Keymaster) to wait upon, and assorted obelisks and hieroglyphs. At its summit, there was a bright light. It was seen in Dana Barrett's refrigerator--in Gozer's own dimension--and in the top of Dana's apartment. Also, an engraving of a scene with the Temple portal and statues of its two minions, can be seen at the top of 550 Central Park West.
Once Zuul and Vinz Clortho completed their ritual, a portal opened and Gozer crossed over from the temple onto the physical plane. The Ghostbusters crossed the streams and destroyed the temple (and part of 55 Central Park West). They were later sued by every city, county, and state agency, effectively forced out of business.
Secondary Canon History
According to the writings of the Cult of Gozer, circa 2800 BCE, Tiamat guided her followers to banish Gozer from the physical plane. A massive interdimensional crossrip was triggered by her followers and Gozer was banished. The Gozerian temple in Shuruppak burned for 9 days under blood red skies and the populace was afflicted with a host of misfortunes comparable to the Biblical plagues of Egypt.
1000 years ago, give or take, as a protracted civil war between the Autobots and Decepticons came to an end on Cybertron when the former left the planet. The Decepticons were unable to pursue them due to the arrival of Gozer from its temple atop one a building. Shockwave, Starscream, Megatron, and Soundwave approached the Temple of Gozer. Gozer announced "The Traveler has come." Megatron demanded it to explain itself or face his wrath. Shockwave warned against antagonizing it and cautioned against its power was beyond his sensors' ability to categorize. Starscream had enough of their inaction and fired at Gozer. Gozer blocked his attack with its right hand then countered with lightning. Megatron berated Starscream. Soundwave suggested broadcasting a distress beacon. Starscream thought the Decepticons should have fled the planet, too. Megatron stated they did not flee and declared he would deal with Gozer himself. Megatron walked up the temple stairs. Vinz charged and leaped at him. Megatron knocked him aside. Megatron walked up to Gozer and asked why it came to his world. Gozer replied to came to end Cybertron and implored him to choose. Megatron didn't understand. Gozer explained it was time to choose the form of their destruction then quickly stated it was done. Starscream became worried. Shockwave asked him what he did. Starscream claimed he did nothing but had a fleeting thought about how he could be mighty enough to destroy the planet. Gozer's Destructor form manifested, a larger version of Starscream. Megatron shot Starscream in the right shoulder. He vowed he would pay for his indiscretion then ordered the alarm to be sounded. The other Decepticons rallied to them. It was not enough and Cybertron was destroyed.
The Temple of Gozer appeared in part of Ray Stantz's precognitive episode. However, a magical obsidian recreation was reassembled by Idulnas soon after, to serve in Gozer's rite of change. In its new state, it was also adorned with a crystalline motif similar to Idulnas' appearance. Once the Re-Selection took place and Idulnas vacated the physical plane, the temple disintegrated. As the Ghostbusters explored more and more dimensions with their Interspatial Teleportation Unit, they observed more and more versions of the Ghostbusters, their logo, flight suits, and Firehouses. It only lent more credibility to the theory they sent the idea of Ghostbusters into the Multiverse when they crossed the streams on the Temple of Gozer. By way of Gozer's portal, for a split second, they took themselves to the line of complete subatomic destruction and were connected to every reality at once. Every thought they ever had, the very core of their beings. their concepts, and their methods were seeded into the subconscious of the Multiverse.
In an alternate timeline, the Ghostbusters decided not to cross the streams on the Temple of Gozer. 31 days later, the Ghostbusters agreed to help Gozer return to its home dimension because it hated its new Destructor Form. They came up with a plan to utilize Tempore Ruga to send Gozer back in time to before Ray chose the form and it would return through the portal. As a precaution, the Ghostbusters went behind Gozer's back and traveled back in time. They posted pictures of an animated character named Loofajoe Rectangleshorts all over the temple. If Gozer betrayed them, then the pictures would reinforce the Ghostbusters to choose Loofajoe, an even worse form for Gozer. Ruga instructed it to concentrate on the precise moment in time where it needed to return. Ruga then flew into the Stay Puft Marshmallow Man's head and Gozer returned to the point before it told the Ghostbusters to choose a form. It saw the posters of Loofajoe and realized what happened. To the past Ghostbusters' confusion, it declared they won and anticlimactically went back through the temple's portal.
Ghostbusters: The Board Game
Just as he was being trapped, Ivo Shandor transported the rooftop of the Shandor Building back in time to before Gozer was banished. The Ghostbusters now had to battle Gozer once more. They crossed the streams to seal the Unison Spirit World Gates and defeated Gozer.
John DeCuir devised and supervised the construction of the Temple of Gozer set which cost around $1 million. It would be famous for being one of the biggest indoor sets ever built in Hollywood.  DeCuir prepared a small foam core study model. Using a makeshift viewer, Ivan Reitman and Richard Edlund used the model to start plotting out camera angles.  
40 matte paintings were created with photos and concept drawings. The enhanced skyline around the temple was done through animated lightning effects and injecting clouds of paint into a giant water tank.  
The power requirements for the set were so intense that during filming, other parts of the studio had to be shut down whenever full illumination was used.  A giant cyclorama encircled more than three-quarters of the temple set and which could be lit for either daylight or nighttime exposures. Shots that needed optical enhancements were filmed from a steady, rigid platform. All other shots were taken from a Chapman crane.   The portal was plexiglass. To simulate smoke, dry fog was pumped during photography. Concealed operators manipulated the Terror Dogs while they rested on the pedestals.  The seismic disturbance caused by Gozer was done practically with sound effects and stagehands throwing rubble. 
Once the preliminary shooting was completed, the main unit went to other sets while DeCuir's team redressed the set as the demolished version for the final scenes in the movie. 
- According to the August 5, 1983 draft of the movie script, the Temple of Gozer is an exact replica of a Sebouillian temple.  
- In the 1984 featurette "On the Scene with the Ghostbusters," found in the 'Ghostbusters Grab Bag' section of the DVD special features, Dan Aykroyd described the Temple of Gozer as a pre-Sumerian temple. 
- The Temple of Gozer was in part inspired by the book "Rooftops of New York" 
- The whole rooftop sequence took a few weeks to film on a stage. 
- In preparation for the detonation of the temple, Thaine Morris had Mark Stetson and this team wield up a frame of steel that was a quarter inch thick on the temple. Deflector aprons were also discussed to deflect the blast out the sides and help simulate the explosion described in the original illustration.  
- On page 22 of Legion Issue #4, Louis Tully alludes to the Temple of Gozer.
- In Ghostbusters: The Video Game (Realistic Versions), while the temple doesn't show up in the finished video game, work is done on a level featuring it. 
- The Temple of Gozer level pitch involved an appearance by Zuul and Vinz Clortho. 
- On page 18 of Ghostbusters Issue #15, Egon Spengler refers to the Temple of Gozer.
- The Retailer Incentive Wraparound Cover of Ghostbusters 101 #1 uses the PR photo from the team at posing at Gozer's altar.
- On page 17 of Ghostbusters Crossing Over Issue #1, in panel 1, in the mini portal is Chevy Chase in an outfit he wore during a set visit of the Temple of Gozer.
- The pose of him pointing at himself is based on a photo he took wearing his "Yes, It' My Real Name" T-Shirt.
- On page 2 of Transformers/Ghostbusters Issue #1, behind and above them is the background from Transformers: The Movie's title sequence when the camera dives into an "O".
- On page 4 of Transformers/Ghostbusters Issue #1, in panel 4, the two statue faces are based on two Quintesson Judges, Death and Rage. The Quintessons are the race who created the Transformers and were overthrown then ousted from Cybertron.
- On page 4 of Transformers/Ghostbusters Issue #1, instead of Ray, it is Megatron who goes up the stairs to address Gozer.
- On page 5 of Transformers/Ghostbusters Issue #1, in panel 1, the dragon and figures on the temple door is visually based on the hieroglyph that Grimlock taps in the Transformers episode "Madman's Paradise".
- On page 6 of Transformers/Ghostbusters Issue #1, in panel 3, the two ends of the temple roof bears the two statue faces of the Quintesson Judges, War and Wisdom.
