Starting at Archway Tube, walk down the right-hand side of Holloway Rd. It's worth going a few metres down the Grove to see the very quaint early school next to the church.
Walk back to Holloway Rd leaving St John's church on your right. Have a good look at the tower as you pass. The church was designed by the architect, Sir Charles Barry, whose most famous building is the Houses of Parliament. This church's tower is said to resemble the square tower of Parliament. The church has another claim to fame - it's a clone of one built in Essex Rd. There was a huge church building scheme in the 1820's, spurred on by parliament's fears that there might be a revolution. They voted a million pounds for church building (at least fifty times that in today's money) presumably with the hope of stabilising society. This church (and its twin) was part of that panic measure.
Continuing down Holloway Rd, past Upper Holloway Station and a short parade of shops you come to Whittington Park. It's unmistakeable because a giant Dick Whittington's cat, made out of plants, sits at the entrance.
Go into the park and follow the path besides the cycle route. When that bends to the left, you might want to take a short detour over to your right (look for wooden decking) to see the wildlife pond.
Rejoining the path besides the cycle route, leave the park. (There's a café on your right, immediately at exit, run by local residents.) Turn to your left and then first right into Tytherton Rd. Beside number 24 is a short lane which leads into Foxham Gardens. It's a tiny park but a complete contrast to one you've just left. It's shady and secluded with a tiny rose garden at its heart. Follow the winding path though the trees to a gate at the far end. Continue on the street in the direction you've been walking and a few yards aheads you'll see a playing field. Follow the right hand edge to a gate in the railings and you'll emerge at the foot of a few steps. Climb the steps. You're now in Station Rd (named for the abandoned Junction Rd Station). Turn left uphill and in a few seconds you'll find yourself on Junction Rd (turn right to return to Archway station.) An opportunity to do some shopping!
