The Fourth of July Fourth, Independence Day, is a federal holiday commemorating the adoption of the Declaration of Independence on July 4, 1776. The Continental Congress declared that the thirteen American colonies regarded themselves as a new nation, the United States of America, and were no longer part of the British Empire. This is a very important day in the history of our country. The managers and Board members of the Historic Sam Houston Schoolhouse salute the people whose sacrifices have made our independence possible. We want to wish you and your family a very safe and happy Fourth of July. The Schoolhouse is closed on Sunday and Monday, to allow our managers and volunteers time to commemorate the Fourth we will be closed Sunday July 1 – Wednesday July 4 and reopen on Thursday July 5th. Please make plans to visit us soon.
