Alec Gerrard, a 78 year old from the United Kingdom, spent 3 years researching his 1:100 scale model of the Bais Hamikdash, that took him 33,000 hours to date and measures 20' x 12'.
He hand painted every clay brick and tile and sculpted all of the 4,000 half inch, correctly dressed figures to populate his creation.
Mr. Garrard began this project in his 40's and does not expect it to be fully completed in his lifetime. All I can say is WOW!!
