MURAL 1 - Shielding the Serpent (Metamorphosis)

This mural is a short distance northwest of the Paititi Market Base Camp and just outside the west entrance to the market. It's sitting at the back of a small, raised pool with an irrigation stream feeding it from above. (Click screenshot to enlarge.)

MURAL 3 - Silver-Crowned Mountain (Metamorphosis)

Scale the climbing wall northwest of the Temple District Base Camp. Then follow the path along the ledge, past relic #5, until you come to the mural. (Click screenshot to enlarge.)

MURAL 5 - God of Learning (Pantheon of Gods 3)

This mural is in one of the caves on the southwest side of the city. The cave has openings at both ends, so you can approach from either direction. If you start at the Village Caves Base Camp, exit the cave, and climb the manmade stone ledges with the irrigation channels on the left, you'll end up at the base of a long staircase leading up to the west. Climb all the way to the top of these stairs and the cave entrance will be directly ahead. Inside the cave, you'll find various collectibles, including relic #7 and document #3 and this relic. The mural is just inside on the left. (Click images for more and larger screenshots.)

MURAL 7 - Deadly Earth Mother (Pantheon of Gods)

A little way south of the bridge leading to the upper city, along the west bank of the river, you can find this mural where the stone irrigation canal empties into the river. (Click screenshot to enlarge.)

MURAL 9 - Founding of Paititi (Founding Paititi)

This mural is in the farmland about halfway between the Paititi Market Base Camp and the Fishing District Base Camp to the north. If you're having trouble finding it, exit the market on the west side, turn right, and continue across the small wooden bridge where a Jaguar Warrior stands guard. Look for an L-shaped stone wall just ahead on the right. The mural is built against this wall. (Click screenshots for more and larger images.)

MURAL 11 - Mirrors (Secrets and Lies)

The next three murals are in the Temple of the Sun Challenge Tomb. If you've already completed the tomb but missed this particular mural, fast travel to the Temple of the Sun Base Camp inside the tomb. Climb down into the hallway to the east (not the one to the west, which leads to the mirror puzzle room). This mural is in the dead-end passageway to the north. If this is all you need, climb back up to the camp and fast travel away. (Click image for more and larger screenshots.)

MURAL 13 - Fertility God (Pantheon of Gods 3)

This mural is in the southeast corner of the mirror room in the Temple of the Sun Challenge Tomb. If you've already completed the tomb but missed this mural, see the bug note below. Fast travel to the Temple of the Sun Base Camp and swing/rappel down into the hallway to the northwest. Follow the passageway to the west and crawl under the door into the mirror room. Use mirror #1 to rotate the beam on the left. Cross over to the northeast corner. Use mirror #2 to rotate the next beam, enabling you to reach the ledge halfway along the east side of the room. (The exit from the tomb is here, but don't leave yet.)

The next beam should already be in position, allowing you to climb across to the southeast corner to reach the mural. When you've examined it, return to the doorway on the east side of the room. Climb the slats to reach the tunnel and follow it back to civilization. The tomb walkthrough has details. (Click image for more and larger screenshots.)

MURAL 15 - Unuratu's Uprising (Rebellion of Paititi)

This mural is in the caves southwest of the city, on the way to the Belly and Head of the Serpent. If you missed it, fast travel to the Belly of the Serpent Base Camp. Climb the stairs and follow the tunnel to the southwest. When you emerge in the next room, the mural is just ahead on the left. (Click image for more and larger screenshots.)

MURAL 17 - Ancient Aqueduct (Trials of the Gods)

This mural is on the way to the Ancient Aqueduct Challenge Tomb, east of the upper city. If you haven't explored this tomb yet, fast travel to the Temple of Kukulkan Base Camp, which appears once you've finished the Porvenir Oil Fields level. Then follow the tomb walkthrough.

If you raided the tomb but missed the mural, instead fast travel to the Subterranean River Base Camp. Follow the passageway to the east, past the point where a brief cutscene shows Lara stowing her weapons and putting on her Serpent Guard mask. The mural is just ahead on the left. (Click image for more and larger screenshots.)

MURAL 19 - Uturunku, The Ferryman (Resting Places)

This mural is in the same area as mural #18 (above). Follow the same shortcut to the crypt and you'll find it just outside the crypt. The shortcut guide also explains how to get back to the base camp. (Click screenshot to enlarge.)

MURAL 21 - Ollanta, The Potter (Resting Places)

This mural is in Ollanta's Crypt, west of the city in the same area as the Path of Battle Challenge Tomb. If you haven't explored there yet, follow the Champion's Bow Side Mission walkthrough. If you've already been there, fast travel to the Wild Jungle Base Camp and follow the stream south to a pool. Climb the ledges to the crypt entrance and proceed to the large, cylindrical room with many ledges. The mural is on the ground level just below the entrance. The crypt walkthrough has details and additional screenshots. If this is all you need, climb back up and return to the Wild Jungle Base Camp the way you came. (Click image for more and larger screenshots.)

MURAL 23 - Path of Battle (Trials of the Gods)

This mural can also be found in the Path of Battle Challenge Tomb west of the city. If you explored the tomb but missed the mural, return to the Ossuary Base Camp. Go through the opening to the southwest. Head down the short flight of steps then turn left and jump over to the ledge that runs along the south wall of the cavern. Follow that ledge to the end and rappel/swing down to the large doorway with the round platform. Continue along the path to find the mural on the left before the tomb proper.
