A place where you get to see bits and pieces of the Spanish influence in the Philippines. Intramuros means walled city, it was created by Spaniards to protect the city from invasion.
This is where you can find the famous Manila Cathedral, Fort Santiago and (UNESCO) San Agustin Church. A walking distance from SM Manila/ Manila City Hall.
For tourists who would like to commute going to Intramuros, you can take the MRT/LRT. This, however, will require you to walk about 500m.
Ride an MRT (south bound) and get off at the last station (Taft) where it connects to LRT. From MRT Taft, take the exit to your right and walk towards the LRT station. From there, you can ride another train and get off at Central Terminal Station (remember that there are six stops before reaching Central Terminal).
From the Central Terminal, you can walk towards a building with huge clock tower (that is Manila City Hall, btw). When you reached Manila City Hall, turn right and walk towards Padre Burgos St-- the main road (if you see a wide road with lots of jeepneys, you are in the right track).
From Padre Burgos St, you can walk towards the underpass to get to the other side of the street. After that, you can walk towards Victoria St where Intramuros entrance is located.
