This is a lighthouse inside a fertilizer factory in Aceh, Indonesia.
This lighthouse is used as a marker for ships entering the pier to transport fertilizer produced by limited companies. But now, the lighthouse is no longer functioning because the fertilizer factory has been closed with certain policies.
In addition, from a distance, a security forces ship was leaning on the dock to secure the location from things that did not want to happen.
Pictures taken using a smart phone camera. Hopefully friends enjoy it.
