Structures Marked with Time

On my walk, I went into a small park down near where the power plant was, and when I looked over the railing I saw these pieces of a concrete foundation that have fallen over into the water.  When we first moved to Sea Cliff, there was a small restaurant located where this park is now and we dined there a couple of times.  Then the foundation collapsed, and the town demolished the restaurant and drove metal bulkheads around where the park is now.  When I saw the colors on the concrete, it left me with a feeling that these were structures from ancient times.  I really love the colors that the harbor has left on the concrete.
