It has been speculated that the original Magellans cross used for firewood, or used with shaboo.

That is not true. The cross is still in place. Magellan's Cross was originally planted by Ferdinand Magellan on 21st April 1521.

Because of its age and now-delicate state, the cross is encased in tindalo wood. If you look overhead in the building sheltering the cross, you will see a painted mural that depicts the cross' planting. Look at the painting carefully and you will see that the cross is lashed together; a Fort San Pedro painting shows the same scene, but the cross is nailed together.

There is no admission fee to see the cross, but you should consider leaving something in the nearby donation box. You will also find many  vendors at this site, selling items large and small: belts, candles, guitars, etc.
