Dear Dave,
I know of nowhere on earth that provides more opportunities for photography. Valetta is the least of it. Go to 'Clapham Junction' to see the prehistoric cart tracks and cave dwellings; to the prehistoric temples at Mnajdra (m-nai-dra), Tarxien (tar-sheen), Hagar Qim (ajjar 'eem) and (in Gozo) Ggantija (juh-gan-tee-ya), along with nearby Ghar Hasan (Ar Hassan, Hassan's Cave); to Fort Rinella to see the biggest muzzle-loading gun ever made, the Hundred Ton Armstrong; to the public gardens at Xemxija (shem-see-ah) to see the Phoenician apiary; to Mdina (mmm-dee-na), the old capital, and the Roman villa just outside the gates in Rabat; Bingemma, the early Christian catacombs; the Citadella and Rabat in Gozo...
Buy The mAZe, the only half-reliable street map of the whole island; hire a car (this is important!); and start exploring...
With any luck, the (paid) Malta travel guide on
www.rogerandfrances.com will be free in the next week or two, on a new site (my web-master keeps saying 'next week').
The language is fairly close to Palestinian, but written in the Roman alphabet: hence 'x' for 'sh' and 'q' for the glottal stop (think of a Londoner saying 'gotta' -- the 'tt' comes out the same way as 'q' in Maltese, sometimes represented by an exclamation mark in transcriptions, hence gor!ah). It's phonetic but you need to know the rules: courgettes (zucchini) are qara baghli ('ara bah-lee -- g+h-with-a-line-through-it is silent), ghaxar (asha) is the number 10, and so forth. English is widely spoken but a few words of Maltese really wins friends.
When are you going? The whole place is pure magic, apart from the really awful tourist enclaves such as Qawra ('Ow-rah) or San Gwann (San Jwann).
Edit: to counter an earlier post, fenech stufat (fen-ek stew-fat, stewed rabbit), is delicious; hobz (Maltese bread) is among the best in the world; pastizzi (cheese turnovers in flaky pastry) are the perfect snack. The wine is indifferent and expensive; the best cheap stuff is Marsovin Rosé. Im-qarrun fil-form (im-ak-roon fill-forn) is baked macaroni and very good; and I like qarnita stufat ('ar-nee-ta stew-fat, octopus stewed in wine with tomato sauce).
And the pizzas I've had in Malta are the second worst I've had anywhere (only India has been worse).
Cheers,
Roger
