Spawning near a beach in a some-what remote location we have 2 Ocean Monuments a short distance from the spawn point. From the spawn point if you walk to about X: -8.456 ,Y:63.00000 Z: 163.706 facing North of the ocean and have your render distance set to at least 17 or above you should see the first monument to the west and the other to the East. From experience there is not much else in this spawn however and you appear to be quite isolated from any nearby villages. Be warned in survival these things are an absolute pain in the butt to try and conquer, I recommend having at least a diamond sword and some Iron Armor as well as plenty of water breathing and night vision potions and a good supply of food and healing potions before you try and even attempt these, there are 3 Elder Guardians you must defeat before you can even attempt to mine any of the treasure located within as getting too close to the monument will make an Elder Guardian trigger a curse on you that gives you mining fatigue 3....
