I can't quite picture the following scene from Chapter 93 in my mind. Could anyone help clarify?

"Langdon was now face to face with the rear wall of the niche. He had no doubt that this tiny space behind the tomb would become his grave. And soon, he realized, as he saw the barrel of the gun appear in the opening beneath the sarcophagus. The Hassassin held the weapon parallel with the floor, pointing directly at Langdon’s midsection.
Impossible to miss.
Langdon felt a trace of self-preservation grip his unconscious mind. He twisted his body onto his stomach, parallel with the casket. Facedown, he planted his hands flat on the floor, the glass cut from the archives pinching open with a stab. Ignoring the pain, he pushed. Driving his body upward in an awkward push-up, Langdon arched his stomach off the floor just as the gun went off. He could feel the shock wave of the bullets as they sailed beneath him and pulverized the porous travertine behind. Closing his eyes and straining against exhaustion, Langdon prayed for the thunder to stop."

Does this take place at Saint Victoria's tomb in the Chapel of St. Joseph, across from the "Ecstasy of Saint Teresa" sculpture?
