On my first trip in the United States , I went to San Antonion . I was on foot . So I went to only three places there : the Alamo , the River Walk , and the Art Gallery . I especially enjoyed visiting the Alamo , a well- known building in America . When I arrived at the Alamo , I was deeply impressed because it was well kept and in good shape . The Alamo was erected in about 1722, was later used as a fort  , and has been kept as a state monument  to the Texan War of Independence against Mexico . During the battle , all of the Texan defenders were killed . I was surprised at the exhibition of rifles , guns , cannons and swords . I was especially attracted by the paintings of a war . The paintings expressed the feelings of a painter very well . Even thought about 160 years have passed since the Battle of the Alamo , the exhibit is well kept . When I came out after seeing the exhibition , I felt as if I had a victory . The outer wall of the Alamo was destroyed here and there . When I touched the wall , I could feel the damage . After the war , little remained of the Alamo . All of the windows and doors were destroyed . The top part of the gate way disappeared without a trace  . I will remember the Alamo forever . It is one of the best places to visit in San Antonio . Which of the following may be the best title for this passage ?
A Famous Building in America My First Visit to America . The Texan War of Independence against Mexico . My Impressions of the Alamo in San Antonio , Texas .
