You will need to visit and collect information in three places before you can calculate the container's final location:
- a. Cross on the top of the hill (N39º 30,895 W009º 08,319): notice the date in roman numbers, which will be value A
- b. Saint Anthony’s Chapel (N39º 30,852 W009º 08,384): notice the date in the end of the poem by Francisco Menezes depicted in the exterior to the left side of the entrance, which will be value B
- c. Lighthouse (N39º 30,636 W009º 08,600 - the same coordinates given/used as start point for the cache): notice the total number of solar panels assembled close together (you will need to take a close look), which will be value C
Now do the following calculations (unit is 0,001 of minutes in DD MM,MMM format):
Final Latitude = Initial Latitude + [(B/C)*2] - 11
Final Longitude = Initial Longitude + (A-B) + 11
A word of advice/warning: Avoid doing this cache with rainy weather; the ground gets slippery and it is potentially a big fall!!
:: S. Martinho
The current bay of S. Martinho is the last vestige of an ancient Golf which, until the 16th century, extended itself inwards to Alfeizerão. It opens to the ocean through a small mouth, around 180 meters large, between the hills of Santana, to the South, and the Lighthouse, to the North (check the photos below).From the top of the belvederes of Facho and Cruzeiro, near the Chapel of Saint Anthony, it is a pleasure to take a look at the bay coloured by the typical yellow fishing boats and by the silvered track of small recreational ones.
The town, founded by the monks of the Monastery of Alcobaça at the 13th century, goes down in the shape of an amphitheatre from the hillside to the Dock, in the northern corner of the Beach. Over recent years it was progressively extended through the Marginal Avenue to the dunes of Salir. Its ancient houses can be discovered by climbing the D. Pedro V lane to the scenic spot of José Bento da Silva Square, or to the Main Church, from the 18th century.
S. Martinho do Porto has many possible walking routes, esplanades, pubs and restaurants for you to discover. The sea is astonishingly quiet and the beach a paradise for children and nautical sports.
