"You haven’t truly experienced Texas until you’ve visited the hallowed grounds of the Alamo. Established in 1718 as the Mission San Antonio de Valero, the building is best known as the site of the 1836 Battle of the Alamo, a 13-day siege under Mexican president General Antonio López de Santa Anna that ultimately killed nearly all of the Texan defenders. To stroll past the limestone facade and envision the battle that played out here is truly a once-in-a-lifetime experience. For a real treat, book an after-hours tour and get the Texas landmark all to yourself as you walk in the footsteps of the fallen soldiers."
