"This "secondary cache" can only be found with
international team-working because:
This cache is just one cache of a set of 30 caches
named European IMC No. 1 … (IMC = International
Multi-Cache). These caches are hidden in 15 European countries:
Austria (A), Belgium (B), Denmark (DK), Finland
(FIN), France (F), Germany (D), Great Britain (GB), Hungary (H),
Ireland (IRL), Italy (I), Luxembourg (L), Netherlands (NL),
Portugal (P), Spain (E) and Sweden (S).
In each country there is a "primary cache" and a
The 15 primary caches are named "European IMC No.1
P-x - yyy" and the 15 secondary caches "European IMC No.1
S-x - zzz" where x is the country code given above and yyy
and zzz can be any additional name.
The primary caches are almost like traditional caches. The
only difference is, that they contain beside the "normal" content
(stash-note, logbook, pencil, give-aways) a "lists of hints" for
the secondary caches.
To be able to search and find a secondary cache you need
all hints from all 15 primary caches!
As the primary caches are scattered all over Europe it
will either require a lot of travelling or - and that is the
intention of the European IMC No. 1 - international
If you want to find this secondary cache, you
1. Find a primary European IMC No. 1
cache (Castelo de Bode area).
2. Contact finders of other primary
European IMC No. 1 caches and exchange the hints.
3. Puzzle the hints together and
4. … email me the hints to get from me the
the final coordinates of this one (see note below in the waypoints
area) and...go and seek the secondary cache.

In the ages where the sources of power became
scarce and were limited only to the muscular force, to the wind and
chains, the tide mills had a great advantage over other forms of
energy: its constancy and previsibility. Two daily tides exists
what guarantees about 4 hours of milling. They were constructed in
the estuaries of the rivers in low lands, and sheltered zones that
allowed to dam waters.
The first tide mill that it has knowledge
appears in c. XII in the south of France. During c. XIII and XIV
they had become enlarged for all the Europe. In Portugal the first
reference of tide mills mentions it in "Castro Marim" in 1290. In
1313 it has notice of one in "Alcântara (Lisboa)" and 1386 in
"Montijo". In 1403, Nuno Álvares Pereira, that was owner of almost
all the lands bathed by the arm of "Tejo" river that enters in the
"Seixal" area, ordered the construction of the mill of "Corroios",
the first one that was risen in that area. In 1404 the goods that
had in the zone of "Seixal", including the tide mill, had been
donated to the Convent of "Carmo". From c. XV the "Carmelitas"
promoted the construction of other mills in that area: the mills of
"Raposa", "Galvão", "Capitão", "Passagem" and "Torre". Other mills
raised in the left edge of the "Coina" river, in this century too.
With the earthquake of 1755 almost all mills had been in ruins
having been in its bigger part restored or exactly rebuilt.
In almost all the estuaries of the Portuguese
rivers mills has built, but the region of "Seixal", consisting of
low land and flooded by the estuaries of "Tejo", facilitated its
construction. In c. XVI, between "Almada" and "Montijo", has been
observed about 60 devices! Next to the mills ports existed where
the boats used in the transport of flours and the transport of the
region's products began.
Already in this century some mills had other
uses. They prepared fish flour, seasonings and peeled rice. Many of
them had arrived until our days, but the "Corroios" tide mill kept
to work until the 70s. This mill, apt to function, was acquired by
the City council of "Seixal" in 1979 that kept it safeguarded and
open to the public as an industrial monument.
In the Natural Park of "Ria Formosa", near
"Olhão", it conserves an exemplar of the existing mills in our
country, also opened to visits and in perfect condition of
functioning. It functioned since its construction, in 1885, up to
1970. The mill of "Marim", equipped with six millstones, was
recouped in the decade of eighty for the National Service of
Still in the "Algarve", they still exist about
of twenty mills in the river "Arade" between "Portimão" and
"Silves", almost all in bad state or reduced to ruins, but they
certify the importance that they had long time ago for the local
economy. In the Municipal Park of "Sítio das Fontes" close to
"Estombar" about three kms from the estuary of river "Arade", there
is the only unit, with the miller's home, to work in full producing
the flour with wich the local bread is cooked. The recovery of this
tide mill and all the environment around is due to the City council
of Lagoa efforts.
During the flood, the casters are stopped and
the floodgate of the boiler opens automatically with the force of
the water that enters.
When the tide starts to leak, the floodgate closes with the
contrary force of the water. The water in the boiler is remained
dammed until the difference of the height of the tide during the
ebb tide puts the casters short. The doors of the pipes to the
casters confide then that, on to the millstones, start to grind
until the beginning of the flood.
To notice that the hours of the tides compelled
the one that it at any time of the day or the night therefore the
mills alone worked during the ebb tide. The other hours were used
to advantage for cleanness and maintenance of the whole set. For a
better exploitation of the system, some boilers of the mills were
used to advantage as fisheries of fish and oysters.
To hunt this cache, You'll have visit to the IMC Nº1 primary
cache in Portugal (Castelo de Bode), take a hints sheet, exchange
the hints you found with finders of the other European IMC Nº1
caches and email me the final set of hints for Portugal, and I'll
send you the coordinates of this cache (see note below in the
A container with the usual stuff and some documentation about
the tide mills.
