Toledo's massive Alcázar, one of the city's most magnificent buildings, is an imposing citadel that…read moresits atop one of the city's most historic sites. The Romans built the first palace here in the 3rd Century, and its ancient foundations can been seen in the massive foyer of the military museum that now calls the Alcázar home. Those foundations, now displayed as part of one of the largest archeological excavations in Spain, are the most interesting part of the massive complex, much of which was reconstructed following the palace's destruction in the 1930s, after a two-month siege by Franco's Nationalist forces.
The Alcázar's fascinating role in the Spanish Civil War (it's basically Spain's version of the Alamo) isn't given the attention it deserves in the present museum, which focuses on Spain's military history from the Visigoths to World War II. The exhibits are interesting (particularly the collection of medieval armor and swords), but they seem random and disconnected, and the lack of detail on the history of the palace itself feels like a missed opportunity. Worth maybe an hour of your time, unless you're a military history buff, in which case it's probably worth two.
