This cache takes you to the chapel of St Paul in the San Pawl tat-Targa area in Naxxar. An area known for some very nice houses and a number of pirate-related and religious legends. Some mild stealth might be required as people like to walk in this area.
Congrats to ch220 for the FTF!

To find out the final coordinates of the cache you need to answer the following questions, the answers to which can be found around the chapel of St. Paul. Use your eyes and do not trust solely on the informational signs (although these are neccesary for some questions). Please bring own pen/pencil. There are a couple of trinkets in cache, which are up for trading.
Please be careful crossing the road, as cars like to speed down this road.
A - How many benches are in the little piazza in front of the chapel?
B - How many years after the chapel was built was the statue of St Paul erected?
C - How many doors does the chapel have?
D - What is the date etched by a Borg in the facade, in the top left side of the chapel's main doorway?
E - What is the most common letter in the Latin inscription on top of the main doorway? The correct answer will be the numerical position of this letter in the Roman/Latin Alphabet.
F - What year was the stone column built?
G - What number is on the Captain's green door?
Use the answers to the above questions to solve the following formula. This should give you the coordinates of the cache.
(hints: Year dates should be used in full. Work out the inner bracketed math operations first. Square brackets represent final solutions and should not be used to work out any more of the solution)
N 35° (D-F-B)/E.(G+B-A)
E (A+3+E)° B-(A*E).((A*C)+E)(E)
