Congrats on the landscape, especially the water and waterfall! I also like the natural looking earth path. The building is nice, though I don't understand why the abutment continues in the upper roof part. The hebrew writing in the catholic windows came as a surprise.
The middle two are clearly Aleph and Mem, The first one looks like He, but could be Het or Tav. The last one could be a final Nun (on a catholic building that would
be a statement) or Vav. Then the yellow cheeseslopes might mark the vowels. If that's true, I don't understand the one with the Aleph. There exists no vowel placed above the baseline on the right side of a consonant. The last vowel must be Shuruk.
So that reads hmn, hmv, h(?)mnnu, h(?)mvu, or even some variation starting with a t.
I do like puzzles, but I don't speak, understand, nor read Hebrew. Couldn't you just use plain old tengwar? Elvish is so much more readable...
